Athletics competitions at the 2015 Pan American Games in Toronto were held from July 19 to 26 at the newly built CIBC Pan Am and Parapan Am Athletics Stadium, located on the campus of York University. The racewalking and marathon events were held on the temporary circuits around the Ontario Place West Channel. The sport of athletics is split into distinct sets of events: track and field events, road running events, and racewalking events.

York Lions Stadium is an outdoor sports stadium on the Keele Campus of Toronto's York University in the former city of North York. It is home to the York Lions, the varsity teams of York University, the Toronto Arrows of Major League Rugby and York United of the Canadian Premier League. The facility was primarily built for the 2015 Pan American and Parapan American Games, where it hosted track and field events and the opening ceremony. In 2021, the stadium's running track was removed to expand the playing surface used for football and soccer.
