List of US 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 listed below. Among the states, the Nebraska Legislature is the only state with a unicameral body. However, three other jurisdictions – the District of Columbia, Guam, and the U.S. Virgin Islands – also have unicameral bodies.

Notes
- The Constitution of California names it the "California Legislature", but the Legislature brands itself as the “California State Legislature”.
- The Constitution of Louisiana vests legislative authority in "a legislature, consisting of a Senate and a House of Representatives," and refers to it as "the legislature" throughout, without officially designating a term for the two houses together. However, the two bodies do use the term "Louisiana State Legislature" in official references to itself.
- There are 3 additional non-voting seats allocated to sovereign tribal nations within Maine. Since 2018, only one seat (belonging to the Passamaquoddy) is filled; the tribal representavtive is a Democrat but is not counted in this total.
- When Nebraska switched to a unicameral legislature in 1937, the lower house was abolished. All current Nebraskan legislators are referred to as “Senators”, as the pre-1937 senate was the retained house.
- Nebraska's legislature is de jure nonpartisan but senators' political affiliations are publicly known and voting often happens along party lines; the de facto composition is given here.
- The Constitution of Utah names it the "Legislature of the State of Utah", but the Legislature brands itself as the "Utah State Legislature".
- The Constitution of Washington names it "the legislature of the state of Washington", but the Legislature brands itself as the "Washington State Legislature".
- The ruling parties of Puerto Rico are separate from the Republican and Democratic parties.

- “Split” in the sense that each of the two chambers are controlled by a different party (e.g., a Democratic Senate and Republican House) or one chamber is evenly split between parties and thus "hung". The Nebraska legislature, though officially nonpartisan, is de facto Republican-controlled, and listed as such.
