The 2010 CFL season is the 57th season of modern Canadian professional football. Officially, it is the 53rd season of the league. Commonwealth Stadium in Edmonton hosted the 98th Grey Cup on November 28 when the Montreal Alouettes became the first team to repeat as Grey Cup Champions in 13 years, defeating the Saskatchewan Roughriders, 21–18. The league announced on its Twitter page on January 29, 2010 that the season would start on July 1, 2010. As of 2016 this is the most recent CFL regular season to start in July.

As the league approaches the 100th Grey Cup, the CFL will celebrate the 1970s with all eight teams wearing retro-themed uniforms from that era during Weeks 6 and 7. Since Saskatchewan's alternate jersey is a version of the 1970s home jersey, they were the only team to wear both home and away retro jerseys during these games.

Additionally, to celebrate the 100th anniversary of the Saskatchewan Roughriders, the players donned red and black centennial jerseys that the team wore from 1912 to 1947 on July 17 when they played Edmonton at Mosaic Stadium at Taylor Field in Regina.

The CFL will begin a series of annual games in Moncton, New Brunswick during the 2010 season. The first game, marketed under the "Touchdown Atlantic" banner took place on September 26, as the Edmonton Eskimos defeated the Toronto Argonauts, 24–6, in front of a sold out crowd of 20,725 at the new Moncton Stadium. Tickets for the game sold out within 32 hours of going on sale. The success of Touchdown Atlantic 2010 has moved Moncton towards a position of candidate for CFL expansion.
