The Duke of Sussex, 36, has been secretly working on the book for nearly a year which he has since sold to Penguin Random House.
Prince Harry has been working with Pulitzer-winning ghostwriter J. R. Moehringer in a rare move from a senior member of the royal family.
The first draft of the manuscript, currently untitled, is said to be almost completely written with the deadline in October.
The proceeds of the deal are likely to be worth millions and, although the exact financial terms were not disclosed, Prince Harry will donate proceeds to charity, according to Random House.
He has himself confirmed: ‘I’m writing this not as the prince I was born but as the man I have become. I’ve worn many hats over the years, both literally and figuratively, and my hope is that in telling my story— the highs and lows, the mistakes, the lessons learned — I can help show that no matter where we come from, we have more in common than we think.
‘I’m deeply grateful for the opportunity to share what I’ve learned over the course of my life so far and excited for people to read a firsthand account of my life that’s accurate and wholly truthful.’
A statement from the publisher reads: ‘In an intimate and heartfelt memoir from one of the most fascinating and influential global figures of our time, Prince Harry will share, for the very first time, the definitive account of the experiences, adventures, losses, and life lessons that have helped shape him.
‘Covering his lifetime in the public eye from childhood to the present day, including his dedication to service, the military duty that twice took him to the frontlines of Afghanistan, and the joy he has found in being a husband and father, Prince Harry will offer an honest and captivating personal portrait, on that shows readers that behind everything they think they know lies an inspiring, courageous and uplifting human story.’
Mr Moehringer has previously written memoirs for a range of other famous faces including tennis legend Andre Agassi and Nike co-founder Phil Knight.

Prince Harry has signed up to the book deal despite issuing repeated calls for his family’s privacy to be respected.
Markus Dohle, CEO of Penguin Random House, said, ‘All of us at Penguin Random House are thrilled to publish Prince Harry’s literary memoir and have him join the world-renowned leaders, icons, and change-makers we have been privileged to publish over the years.
‘Prince Harry has harnessed his extraordinary life experience as a prince, a soldier, and a knowledgeable advocate for social issues, establishing himself as a global leader recognized for his courage and openness.
‘It is for that reason we’re excited to publish his honest and moving story.’

Robert Jobson, author of the bestseller Prince Philip’s Century, has commented on Harry’s book deal and drawn parallels with former King Edward VIII.
‘As night follows day, this was always going to happen,’ he told MailOnline.
‘It will become an international bestseller, but at what cost to the monarchy? There will be nowhere to hide.
‘It is not the first time a ‘exiled’ senior royal has written a memoir … the former King Edward VIII wrote one.
‘His book – A King’s Story: The Memoirs of HRH the Duke of Windsor, KG – was published to a media storm in the 50s. It caused a sensation.
‘But this is bound to cause mayhem amongst the House of Windsor. If Harry, which seems inevitable, goes into detail about mental health issues involving his wife and alleged racism at the heart of the royal family, it will be hugely damaging to the House of Windsor and the Monarchy as an institution.
‘Harry is already hugely rich and famous so apart from damaging his family – which a book like this will inevitably do, I am not sure what he is trying to achieve. Whatever he says will lead to conflict.
‘No wonder there is a rift between the royal brothers and problems with his father. How can any bridges be built when he is doing this? I cannot see any royal rift ever being healed at this rate.’
The book deal is likely to only increase the tensions between the Duke of Sussex and the rest of the Firm with relations already strained.
Prince Harry has been separated from brother William, 39, by a rift that began in March 2019 when the Duke of Cambridge reportedly threw Harry and wife Meghan Markle out of Kensington Palace over the alleged bullying of staff – with the Sussexes breaking up their joint foundation.
The gulf was exacerbated when the couple, who stepped down from royal duties in early 2020, moved away from the UK to start a new life after citing the desire for a more private life.
But just four months ago Harry and Meghan made worldwide news during their explosive two-hour interview with Oprah Winfrey near the couple’s home in Montecito, California.
Meghan spoke of feeling lonely and nearly suicidal at six months pregnant before the couple left England and Harry acknowledged tension with his father, Prince Charles, over his decision to step back from his royal duties and his marriage to the biracial American actor.
‘There is a lot to work through there,’ Harry said about his relationship with his father, who was divorced from Diana, Princess of Wales, at the time of her fatal car accident in 1997.
‘I feel really let down. He’s been through something similar. He knows what pain feels like. And Archie (Harry and Meghan’s son) is his grandson. I will always love him, but there is a lot of hurt that has happened.’
Harry told Winfrey that he felt trapped by royal life and that his family cut off him financially and took away his security.

Meghan Markle will face an ‘awkward reunion’ with The Firm if Lilibet is christened at Windsor
Meghan Markle could be faced with an ‘awkward’ reunion with the Royal Family if her daughter Lilibet gets christened in Windsor, a royal expert has claimed.
According to royal insiders, the Duke and Duchess of Sussex’s daughter Lilibet Diana could follow in the footsteps of older brother Archie and be christened in St George’s Chapel in Windsor with the Queen present.
However, royal expert Russell Myers has warned that it will be ‘definitely awkward’ as tensions are still running ‘very high within the family’.
‘It will be definitely awkward,’ he said, speaking to Today. ‘Meghan isn’t flavour of the month with the family. Certainly, the family have always said they will be much-loved members of the family.
‘However, we’re still talking about the fallout of the Oprah Winfrey interview, Emmy or no Emmy nomination.
‘The tensions are still running very, very high within the family, indeed.’
A source previously told the Daily Mail: ‘Harry told several people that they want to have Lili christened at Windsor, just like her brother Archie.
‘They are happy to wait until circumstances allow.’
Harry also acknowledged his relations were strained with his brother, Prince William.
‘I was trapped, but I didn’t know I was trapped,’ Harry said, before adding, ‘My father and my brother, they are trapped.’
Meghan also claimed that Kate Middleton left her in tears during a row over bridesmaid dresses and Harry accused his father Prince Charles of refusing to take his calls when the pair moved to the US.
In one of the most shocking sections of the Oprah interview, the duchess claimed that Harry was asked by a close relative ‘how dark’ their unborn baby would be.
She added that the unnamed royal had raised ‘concerns and conversations about how dark his skin might be when he’s born’.
The couple refused to identify the person concerned as it would be ‘too damaging to them’.
Buckingham Palace said at the time that the royal family were ‘saddened’ to hear how challenging the couple’s lives had been.
In the days that followed, Prince William also uncharacteristically hit back at his brother’s claims while visiting a school in east London with wife Kate Middleton.
Sky News reporter Inzamam Rashid asked: ‘Can you just let me know, is the Royal Family a racist family?’
William, who was wearing a face mask at the time, firmly said: ‘We’re very much not a racist family.’
Kensington Palace later declined to comment and said that the duke had said all he wished to say.
Harry and Meghan have since faced criticism for repeatedly complaining about their own privacy being violated at the same time as sharing damaging details about private conversations they have had with senior royals in front of a global TV audience numbering in the tens of millions.
They have also been accused of ‘hypocrisy’ for releasing photos of private family moments on Instagram – prompting press stories of their private lives – while complaining about media intrusion after coverage that paints them in a bad light.
Last month, Meghan published her own picture book ‘The Bench’ through Random House Books for Young Readers.
And this latest venture comes just weeks after the pair, who are parents to two-year-old Archie, welcomed Lilibet ‘Lili’ Diana Mountbatten-Windsor on June 4 at 11.40am in Santa Barbara Cottage Hospital.
The couple had said they would ‘both take some proper time off’ to adjust to life as a family-of-four before stepping back into their various business engagements.
Prince Harry’s paternity leave has meant taking time out from his executive position at a Silicon Valley start-up that claims to be worth $1.7billion.

For the couple the time-off also meant temporarily stepping back from their multi-million-pound deals with Netflix and Spotify – which Harry told Oprah Winfrey he was persuaded to sign when he was ‘literally cut off financially’ from the Royal Family.
It was revealed last month that the couple have so far broadcast just 35 minutes of podcast content on Spotify as part of their £18million deal.
The Sussexes were last heard on their Archewell Audio Spotify podcast for the 2020 Christmas special, and the platform had planned for ‘a full-scale launch of shows’ in 2021.
It is understood that the couple will be paid the full £18million fee after their duties have been met, The Sun said.
