The 2010 Maryland General Assembly elections took place on November 2, 2010, to choose the Delegates and Senators of the Maryland General Assembly. The 2010 U.S. House election, 2010 U.S. Senate election, and 2010 Maryland gubernatorial election occurred on the same day. All 47 seats in the State Senate and 141 seats in the House of Delegates were contested. Democrats successfully defended their current supermajorities in both chambers. In this article, legislative districts are organized geographically rather than by number for ease of locating a delegation. In the primary election on September 14, 2010, a number of sitting Senators were challenged from within their own party. Five Senators lost their primary elections.
