The Pennsylvania General Assembly is the legislature of the U.S. commonwealth of Pennsylvania. The legislature convenes in the State Capitol building in Harrisburg. In colonial times (1682–1776), the legislature was known as the Pennsylvania Provincial Assembly and was unicameral. Since the Constitution of 1776, the legislature has been known as the General Assembly. The General Assembly became a bicameral legislature in 1791. As of 2024, it is the only state legislature in the country in which Democrats and Republicans each control one chamber.
