MLS Cup 2016 was the 21st edition of the MLS Cup, the championship game of Major League Soccer (MLS), which took place on December 10, 2016, at BMO Field in Toronto, Ontario, Canada. It was the second final to be hosted in Toronto, after 2010, and the first there since the cup transitioned away from neutral-site venues. The Seattle Sounders won the cup over Toronto FC in a penalty shoot-out that followed a 0–0 draw.

2016 final was the first to be contested between two expansion teams and became the first in league history to end scoreless. Toronto FC became the first Canadian club to play in the MLS Cup, while Seattle won their first title. The title capped a comeback season for the Sounders, who replaced their manager during the middle of the season and climbed from second-to-last in the conference to a playoff spot.
