The Ohio Senate is the upper house of the Ohio General Assembly. The State Senate, which meets in the Ohio Statehouse in Columbus, first convened in 1803. Senators are elected for four year terms, staggered every two years such that half of the seats are contested at each election. Even numbered seats and odd numbered seats are contested in separate election years. The president of the Ohio Senate presides over the body when in session, and is currently Matt Huffman.

The Ohio General Assembly is the state legislature of the U.S. state of Ohio. It consists of the 99-member Ohio House of Representatives and the 33-member Ohio Senate. Both houses of the General Assembly meet at the Ohio Statehouse in Columbus.
