The Thanksgiving Day Classic is an annual doubleheader held on Thanksgiving in the Canadian Football League (CFL). It is typically one of two days in which the league plays on a Monday afternoon; the other is the Labour Day Classic. Unlike the Labour Day Classic, the teams in the Thanksgiving Day Classic rotate each year. The games also lack a presenting sponsor as the Labour Day Classic games have.
The Montreal Alouettes have traditionally been given hosting duties for the opening game. This was originally started in 1997 to compensate for not being part of the Labour Day Classic festivities; Montreal and the various Ottawa franchises normally play on Labour Day when both franchises are active. The Alouettes' permanent hosting of Thanksgiving remained in place after Ottawa returned to the league in 2014. The Hamilton Tiger-Cats played CFL games annually in all but three years between 1958 and 1982, hosting the vast majority of them; Hamilton also hosted three times in four years from 1990 to 1993 and again hosted a Thanksgiving matchup in 2013 due to stadium construction disrupting their hosting of the 2013 Labour Day Classic.
Despite Canadian Thanksgiving being a legal holiday in the United States (Columbus Day), none of the CFL's American teams ever played the Thanksgiving Day Classic. The games have also not been televised live in the United States since 2009, although one of the two was broadcast on tape-delay in 2013.
