Thomas Paul Latham (born July 14, 1948) is an American politician who served as a U.S. representative for Iowa from 1995 to 2015.

Latham was elected as the congressman for Iowa's 5th congressional district in 1994[2] as part of the wave that allowed Republicans to take over the House for the first time since 1955.

In 1996 he won 65 percent of the vote in defeating Democrat MacDonald Smith, and he ran unopposed in the 1998 election.

For the 2008 elections, it had a Cook Partisan Voting Index of D+0.4, making it one of the most marginal districts in the nation.

Latham, who had moved to Ames, closer to the center of the district, earned 57.3% of the vote as he won reelection.

In the 2008 election Latham won against Democratic nominee Becky Greenwald with 61 percent of the vote even as Barack Obama carried the district by eight points.

Nevertheless, he opted to run in the reconfigured 3rd District, which stretches from Des Moines to Council Bluffs.
