Tillinghast L'Hommedieu Huston (July 17, 1867 – March 29, 1938) was an American civil engineer and businessman. He co-owned the New York Yankees of Major League Baseball with Jacob Ruppert from 1915 to 1923, turning them from one of the worst franchises in baseball into a World Series contender.

A civil engineer by trade, Huston worked for Cincinnati's waterworks before forming a company of volunteer engineers in the Spanish–American War. He was commissioned as a captain, earning him his nickname. He stayed in Cuba after the war as a private contractor, rebuilding infrastructure in Cuba and earning his personal fortune. Returning to the United States, Huston partnered with Ruppert to buy the Yankees in 1915. Together, they used their wealth to acquire talented players who improved the team, including Babe Ruth.

Huston returned to the military during World War I, and was promoted to major and then to lieutenant colonel. Following a dispute, Huston sold his interests in the Yankees to Ruppert in 1923. He purchased the Butler Island Plantation, which had fallen into disrepair, and rebuilt it as a dairy and lettuce farm. Huston resided at the plantation until his death in 1938.
