The 2015 CFL season was the 62nd season of modern Canadian professional football. Officially, it was the 58th season of the league. The Edmonton Eskimos won the 103rd Grey Cup on November 29, defeating the Ottawa Redblacks 26–20 in Winnipeg. The schedule was released February 13, 2015 and the regular season began on June 25, 2015.

According to the new collective bargaining agreement, the 2015 salary cap was set at $5,050,000. As per the agreement, the cap is fixed and will not vary with league revenue performance. The minimum team salary was set at $4,450,000 with individual minimum salaries set at $51,000.

The 2015 season schedule was released on February 13, 2015, with the regular season opening on June 25, 2015 at Percival Molson Memorial Stadium in Montreal, Quebec. It was the first time that Montreal had hosted the season opener since the 2011 CFL season. The major complication this year was the lack of available stadium dates due to the 2015 FIFA Women's World Cup and the 2015 Pan Am Games occurring over the entire CFL pre-season and first five weeks of the regular season, affecting five member clubs. The BC Lions, Edmonton Eskimos, and Ottawa Redblacks played pre-season games away from their regular stadiums and in some instances, in different cities. The Hamilton Tiger-Cats did not play a regular season home game until week 6 and the Argonauts did not play in Toronto for a regular season game until week 7.

Following three straight years of intra-division matchups in the last week of the regular season (and for the last two years, those same matchups in the last four weeks), the league featured inter-division games in the last week. There was also a Sunday game in the last week of the regular season which hadn't occurred since the 2010 CFL season. This season featured seven home-and-home series, up from two from the previous year. Despite Ottawa returning to the league, they did not play the Montreal Alouettes on Labour Day weekend, which is the first time since 2002 where both teams played in the league but did not play that same weekend. There were 15 double headers this year, with four on Fridays, nine on Saturdays, one on Sundays, and one on Labour Day Monday. The league also experimented with games regularly featured on Thursday nights, with one game every Thursday for 10 of the first 11 weeks of the season. The Thanksgiving Day Classic featured just one game for the first time since 1997, which is ironic in that it was the only week of the season with five games being played. For the second straight year, there was no Touchdown Atlantic contest.
