These are the results of the men's K-1 slalom competition in canoeing at the 2004 Summer Olympics. The K-1 (kayak single) event is raced by one-man kayaks through a whitewater course. The venue for the 2004 Olympic competition was the Olympic Canoe/Kayak Slalom Centre at the Helliniko Olympic Complex.
The 25 competitors each took two preliminary runs through the whitewater slalom course. The top 20 kayakers by combined time from the two runs advanced to the semifinal. The top 10 times from the single semifinal run determined the finalists. Ranking and medals are based on the combined time of the semifinal run and the final run. The preliminary runs were raced on August 19 and the semifinal and final runs were on August 20.
