The singer and recent EastEnders actor has signed a deal with publishers Virgin Books to release the title, which will document his four-decade career.
The currently untitled book will be released in March 2012.
Virgin Books editorial director Lorna Russell said in a statement: "David Essex is a legend, and his autobiography has all the stuff of a bestseller, from his gloriously recounted working-class childhood in the East End of London, through the crazy years of Essex mania and beyond. It's completely fascinating, and readers will love it."
Essex added: "With so many adventures I felt it was time to write them down. I hope the reader will enjoy the journey as much as I have."
The star recently said that filming his final scenes on EastEnders was "emotional".
Essex is currently touring his own show All the Fun of the Fair.
