2015 Atlantic Sun men's soccer tournament

The 2015 Atlantic Sun Conference men's soccer tournament, the 37th edition of the tournament, determined the Atlantic Sun Conference's automatic berth into the 2015 NCAA Division I Men's Soccer Championship.

The North Florida Ospreys won the tournament, besting the USC Upstate Spartans in the championship match. The 7–0 winning scoreline was the second most lopsided scoreline in an Atlantic Sun championship, and the largest since 1979.

This was the final edition of the tournament held under the "Atlantic Sun" or "A-Sun" branding. In April 2016, the conference announced a rebranding as the ASUN Conference.
