Lloyd Crow Stark (November 23, 1886–September 17, 1972) was a Governor of the U.S. state of Missouri. He was a Democrat.

Stark was born near Louisiana, Missouri. He was a major in the U.S. Army during World War I. He served as the Governor of Missouri from 1937 to 1941 and was a delegate to Democratic National Convention from Missouri in 1940.

Lloyd Stark had a fierce political rivalry with Harry S. Truman, who he ran against for the Senate in 1940—and lost that election when one of Stark's prominent supporters ran against him and divided the vote among his Eastern Missouri power base. He died in Clayton, Missouri in 1972.

Lloyd Stark was part of a family rather prominent in Missouri and was active with his brother Paul Stark in the then family-owned business Stark Brothers' Nursery (the oldest Nursery in America and at one time the largest in the world). Lloyd Stark was the cousin of Charles Stark Draper and was named by Richard Nixon as one of three people he truly disliked.
