MLS teams also play in other international and domestic competitions. Each season, up to ten MLS teams play in the [[CONCACAF Champions Cup]] (CCC) against other clubs from the [[CONCACAF]] region. Four MLS teams qualify based on regular-season results from the previous year: the [[Supporters' Shield]] champion, the team with the highest point total from the opposite conference, and the next two clubs in the Supporters' Shield rankings. The fifth MLS team to qualify is the reigning [[MLS Cup]] champion. An additional U.S.-based MLS team can qualify by winning the [[U.S. Open Cup]].<ref>{{Cite web |title=Lamar Hunt U.S. Open Cup |url=http://www.ussoccer.com/lamar-hunt-us-open-cup |url-status=live |archive-url=https://web.archive.org/web/20140920220525/http://www.ussoccer.com/lamar-hunt-us-open-cup |archive-date=September 20, 2014 |access-date=September 20, 2014}}</ref> Starting in 2024, the league will send eight teams to participate in the U.S. Open Cup instead of every U.S.-based club, with [[MLS Next Pro]] teams as representatives for some teams.
