List of United States state legislatures
This is a list of United States state legislatures. Each state in the United States has a legislature as part of its form of civil government. Most of the fundamental details of the legislature are specified in the state constitution. With the exception of Nebraska, all state legislatures are bicameral bodies, composed of a lower house (Assembly, General Assembly, State Assembly, House of Delegates, or House of Representatives) and an upper house (Senate). The United States also has one federal district and five non-state territories with local legislative branches, which are also listed below. Among the states, the Nebraska Legislature is the lone unicameral body, although three other areas – the District of Columbia, Guam, and the U.S. Virgin Islands – also have unicameral bodies.
