Thomas Gilbert Loeffler (born August 1, 1946) is an American politician and Republican former member of the United States House of Representatives from central Texas.

The two-term Democratic incumbent, Bob Krueger, gave up the seat to make an unsuccessful run for the Senate.

After four terms in the House, he stepped down to run for governor of Texas but lost a hard-fought Republican primary election to the eventual winner, Bill Clements.

[citation needed] After his congressional career, Loeffler was appointed to the Office of Legislative Affairs as the coordinator for Central American policies.

He later co-founded the lobbying firm Gray Loeffler LLC, representing clients including the Kingdom of Saudi Arabia.
