Zimbabwean-born Fletcher, the most successful coach in England's cricketing history, was to be inducted into Britain's Coaching Hall of Fame and receive the Mussabini Medal from Princess Anne at a ceremony in London on Thursday.
Fletcher's attention to detail and motivational ability has been central to a renaissance which has seen England win successive series against Zimbabwe, West Indies, Pakistan and Sri Lanka.
"I am very honoured to win this award," the 56-year-old said.
"It has been a great year for the England team and I would really like to thank all the England players and the management team for their contributions to the teams success."
Fletcher was born in Harare and became England's first overseas coach when he was appointed in June 1999.
Other coaches honoured on Thursday included Terry Edwards, mentor to teenage Olympic boxing medallist Amir Khan, and Jurgen Grobler, the German rowing coach who played a key role in the Olympic success of Sir Steve Redgrave and Matthew Pinsent.
