The 1998 Canadian Football League season is considered to be the 45th season in modern-day Canadian football, although it is officially the 41st Canadian Football League season.

The Canadian Football League signed a five-year television contract with TSN. With the deal, TSN had the right to all CFL television broadcasts. The league also made a sponsorship deal with Adidas, which made them the official footwear, practice wear, and sport glove provider of the CFL.

For only the second time in history, the city of Winnipeg hosted the Grey Cup game.
