Horizon League men's basketball tournament

Hosting rights for the quarterfinals and semifinals were awarded to the winner of the regular season championship.

Beginning in 2009, the Horizon League secured an entitlement sponsorship of its men's and women's basketball tournaments with Speedway SuperAmerica, a major gas and convenience store chain throughout the midwest United States, officially changing the name of the tournaments to "The Speedway Horizon League Men's/Women's Basketball Championship".

From 2016 to 2019, the Horizon League tournament was held in Detroit under a five-year deal, beginning at Joe Louis Arena, adding the women's tournament in 2017 (with both events marketed under the title Motor City Madness), and moving to the newly-opened Little Caesars Arena beginning in 2018.
