The Michigan Legislature is the state legislature of the U.S. state of Michigan. It is organized as a bicameral institution consisting of the Senate, the upper house, and the House of Representatives, the lower house. Article IV of the Michigan Constitution, adopted in 1963, defines the role of the legislature and how it is to be constituted. The Michigan Legislature meets in the Michigan State Capitol in Lansing, Michigan.
The State Senate is the upper house of the legislature. Its members are elected on a partisan basis for four-year terms concurrent with the election of the Governor of Michigan. The Senate consists of 38 elected from single-member election districts ranging from 212,400 to 263,500 residents according to the most recent creation of districts (2002). Senators' terms begin at noon on January 1 following their election. The Senate chamber in the State Capitol is located in the south wing of the building. As of 2007, Republicans hold a majority of seats in the Senate with 21; Democrats hold 17 seats. Under the Michigan Constitution, the Lieutenant Governor of Michigan serves as President of the Senate but may only cast a vote in the instance of a tie. The Senate selects its other officers and adopts its own rules of procedure at the start of a new legislative session.
The State House of Representatives is the lower house of the legislature. Its members are elected on a partisan basis for two-year terms at the same time at which Representatives in U.S. Congress are chosen. The House of Representatives consists of 110 members who are elected from single-member election districts ranging from 77,000 to 91,000 according to the most recent creation of districts (2002).

As of 2007, Democrats hold a majority of seats in the House of Representatives with 58, and Republicans hold the remaining 52 seats. The House of Representatives selects its own Speaker of the House and other officers and adopts its rules of procedure at the start of a new legislative session.
