Harry, who alongside his wife Meghan stepped back from royal duties last year, will donate proceeds to charity.
According to the BBC, the duke has recently spoken privately with his family about writing the book.
A spokesperson for the duke reiterated that he would not be expected to obtain permission for the project from Buckingham Palace.
They did not provide additional details on what share of the proceeds would be donated to charity.
Penguin did not disclose the terms of its deal, which includes an audio book and international rights.
Becoming of the prince
The duke said in a statement:
I'm writing this not as the prince I was born but as the man I have become.
He added:
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 first hand account of my life that's accurate and wholly truthful.
Markus Dohle, of Penguin Random House, described the duke as being among ‘world-renowned leaders, icons, and change-makers we have been privileged to publish over the years.’
In a released press statement, the book is described as ‘intimate and heartfelt’ and ‘honest and moving.’
It added:
Prince Harry will offer an honest and captivating personal portrait, one that shows readers that behind everything they think they know lies an inspiring, courageous, and uplifting human story.
The Sussexes have established an organisation called Archewell, which has production arms alongside a non-profit foundation.
In May, it was announced that the Duchess of Sussex would publish a children's book, The Bench, about father-son relationships, as seen through the eyes of mothers with the same publisher.
It was said to be inspired by the bond between Harry and their son.
