Greater Manchester Police confirmed a body had been found at Hatton's address and that the death is not being treated as suspicious.
A GMP spokesperson said. "We can confirm that we have found a body at an address on Bowlacre Road in Gee Cross at 6.45am today, Sunday, September 14th. The death is not being treated as suspicious."
News of Hatton's death comes months after he announced his return to boxing with a fight planned for December.
His last professional bout was 13 years ago when he was beaten by Vyacheslav Senchenko in Manchester.
Hatton emerged as one of Britain's most popular boxers and took on fights against Floyd Mayweather and Manny Pacquiao. He had an unblemished 43-0 record until he faced Mayweather in 2007, when he was stopped in the 10th round.
He finished his career with a 45-3 record and held multiple world championship titles, as well as UK titles.
He was named Fighter of the Year in 2015 and was inducted into the International Boxing Hall of Fame as part of the class of 2024.
