The 2003 United States state legislative elections were held on November 7, 2003, alongside other elections. Elections were held for 8 legislative chambers.^[1] Both chambers of the Northern Mariana Islands legislature was up.

Partisan change only occurred in one chamber, as Democrats won control of the New Jersey Senate, which was previously tied.^[2] However, Democrats did maintain control of the Mississippi Legislature, the Louisiana Legislature, and the New Jersey General Assembly. Republicans maintained control of the Virginia legislature, bringing a post-Civil War low for the Democratic Party.^[3]
