The Socialist Party of Louisiana was a political party in the U.S. state of Louisiana affiliated with the Socialist Party of America. The 1912 results reveal that the party's support was based in areas that had been strongholds of the Populist Party in the 1890s. Their areas of highest support were parishes with few large farms and lower farm values. Other important constituencies within the party were unskilled lumber workers and Marxian socialists, who were based in New Orleans.
