Houston Dynamo Football Club is an American professional soccer club based in Houston. The club competes in Major League Soccer (MLS) as a member of the Western Conference. Established on December 15, 2005, the club was founded after their former owners relocated the San Jose Earthquakes' players and staff to Houston following the 2005 season. For their first six seasons in Houston, the Dynamo played at Robertson Stadium on the campus of the University of Houston. During the 2012 season, the club moved to Shell Energy Stadium, a soccer-specific stadium in East Downtown Houston.

The club is majority-owned by Ted Segal. Segal fully controls ownership after buying out his remaining minority partners in August 2022.

The Houston Dynamo have won the MLS Cup twice, doing so during their first two seasons in 2006 and 2007. The club has also won the U.S. Open Cup twice, in 2018 and 2023. They have been MLS Cup runners-up twice, in 2011 and 2012, and Supporters' Shield runners-up once in 2008. The Dynamo have also reached the final of the now defunct North American SuperLiga, finishing as runners-up following a defeat against the New England Revolution.
