The 2011 Houston Dynamo season was the club's sixth season of the team's existence, breaking the record for the most seasons played for a Houston soccer team. The club had been tied with Houston Hurricanes of the D3 Pro League (1996–2000).

Most notably, the Dynamo became the runners-up in their third MLS Cup, falling to the Los Angeles Galaxy 1–0 in the final. The team also made a run in the U.S. Open Cup but lost to the Seattle Sounders in the semifinals. Houston was the champions of the yearly edition in the Texas Derby.

The Dynamo switched from the Eastern Conference to the Western Conference for the 2011 season, after teams were added in Vancouver and Portland.

As of August 7, 2011.
