In a very close final he defeated Scotland's two-time World Champion John Higgins 10-8.
Tournament surprise Stuart Pettman (England) and Ryan Day (Wales) lost out in the semifinals.
Ebdon received £52,000 for the victory and Higgins got £25,000 for his runner-up spot.
Higgins and Ricky Walden (England) shared the £2,000 high break bonus after compining matching 140s.
Defending champion Stephen Maguire (Scotland) crashed out 5-0 to Dave Harold in the first round.
This was the eighth ranking title for Ebdon but first since the 2006 UK Championship. Higgins was looking for his 20th title and second of the season.
Higgins' final loss means the seven ranking events of the season have been won by seven different players.
Ebdon leapt from 17th to 12th in the provisional rankings. Higgins advanced two places, from seventh to fifth. Pettman jumped from 48th to 37th. Ronnie O'Sullivan (England) and Maguire retain the top two positions. Shaun Murphy (England) overtook Allister Carter (England) to claim third place.
