Marion Butler was an American politician, farmer, and lawyer. He represented North Carolina in the United States Senate for one term, serving between 1895 and 1901. At the time, he was a leader of the North Carolina Populist Party, and also affiliated with the Democratic Party and the Republican Party at different points in his career. He was the older brother of George Edwin Butler.

The People's Party, also known as the Populist Party or simply the Populists, was an agrarian populist political party in the United States in the late 19th century. The Populist Party emerged in the early 1890s as an important force in the Southern and Western United States, but collapsed after it nominated Democrat William Jennings Bryan in the 1896 United States presidential election. A rump faction of the party continued to operate into the first decade of the 20th century, but never matched the popularity of the party in the early 1890s.
