The Connecticut General Assembly (CGA) is the state legislature of the U.S. state of Connecticut. It is a bicameral body composed of the 151-member House of Representatives and the 36-member Senate. It meets in the state capital, Hartford. There are no term limits for members of either chamber.

During even-numbered years, the General Assembly is in session from February to May. In odd-numbered years, when the state budget is completed, session lasts from January to June. The governor has the right to call for a special session after the end of the regular session, while the General Assembly can call for a "veto session" after the close in order to override gubernatorial vetoes.

During the first half of session, the House and Senate typically meet on Wednesdays only, though by the end of the session, they meet daily due to increased workload and deadlines.

The three settlements that would become Connecticut (Hartford, Wethersfield, and Windsor) were established in 1633, and were originally governed by the Massachusetts Bay Company under terms of a commission for settlement. When the commission expired in 1636 and the Connecticut Colony was established, the legislature was established as the "General Corte", consisting of six magistrates along with three-member committees representing each of the three towns. In 1639, the Fundamental Orders of Connecticut were adopted, which changed the spelling to "General Court;" formalized its executive, judicial, and legislative authority; and changed its membership to consist of the governor and six magistrates (each elected for one year terms) and three or four deputies per town (elected for six-month terms). Although the magistrates and deputies sat together, they voted separately and in 1645 it was decreed that a measure had to have the approval of both groups in order to pass. The Charter of 1662 changed the name to the General Assembly, while replacing the six magistrates with twelve assistants and reducing the number of deputies per town to no more than two. In 1698, the General Assembly divided itself into its current bicameral form, with the twelve assistants as the Council and the deputies as the House of Representatives. The modern form of the General Assembly (divided into the upper Senate and lower House and devoid of all executive and judicial authority) was incorporated in the 1818 constitution.

Most of the General Assembly's committee and caucus meetings are held in the modern Legislative Office Building (LOB), while the House and Senate sessions are held in the State Capitol. The two buildings are connected via a tunnel known as the "Concourse", which stretches underneath an off-ramp of Interstate 84. Most offices for legislators and their aides are also housed in the LOB, though some legislative leaders choose to be based in the State Capitol itself.

Each committee has its own office space, with most being located in the LOB. A few committees, particularly select committees, have their offices in the Capitol. Committee chairs and ranking members normally choose to have their personal offices near their committee offices, rather than staying in their caucus areas.

The General Assembly is also provided with facilities such as a cafeteria, private dining room, newsstand, and library.

The General Assembly has 26 committees, all of which are joint committees; that is, their membership includes House and Senate members alike. Several committees have subcommittees, each with their own chair and special focus.
