2001 United States state legislative elections

The 2001 United States state legislative elections were held on November 6, 2001, during President George W. Bush's first term in office. Elections were held for four legislative chambers in two states, simultaneous to those states' gubernatorial elections. Both chambers of the Northern Mariana Islands legislature were up as well.

These were the first elections affected by the 2000 redistricting cycle, which reapportioned state legislatures based on data from the 2000 United States census.

Republicans maintained control of both houses of the Virginia General Assembly, while Democrats won control of the New Jersey General Assembly, and evenly split the State Senate. Democrats additionally won control of the Washington House of Representatives through special elections.
