The 1908 Texas gubernatorial election was held to elect the Governor of Texas. Governor Thomas Mitchell Campbell was re-elected to a second term in office.
Campbell defeated State Representative Robert R. Williams in the Democratic primary by a wide margin, which was tantamount to victory in the general election.
Charles L. Martin was a late substitute as the Independence candidate, so his name did not appear on the ballot.
