The 26-year-old’s previous deal was set to expire at the end of the season, but the striker has now signed a new three-and-a-half-year contract with the club.
Becchio told the club’s official website: “I’m very happy to sign the contract and stay at the club.
“I love the fans, we are doing well, and we want to get to the Premier League. I want to be part of that and I’m really pleased.”
“It’s fantastic news that he has signed his contract,” Leeds United manager Simon Grayson.
“He has shown his importance to the club with his goalscoring ability and he has never been the sort of player to shy away from giving 100 per cent.
“It was vital that we secured his services after losing Jermaine Beckford last season, and I believe this shows the ambition we have as a football club.
“It is a major boost for everyone, particularly as there was considerable interest in him.”
