The Kansas State Capitol, known also as the Kansas Statehouse, is the building housing the executive and legislative branches of government for the U.S. state of Kansas. Located in the city of Topeka, which has served as the capital of Kansas since the territory became a state in 1861, the building is the second to serve as the Kansas Capitol. During the territorial period (1854–1861), an earlier capitol building was begun but not completed in Lecompton, Kansas, and smaller structures in Lecompton and Topeka were where the territorial legislatures met.

The Kansas Legislature is the state legislature of the U.S. state of Kansas. It is a bicameral assembly, composed of the lower Kansas House of Representatives, with 125 state representatives, and the upper Kansas Senate, with 40 state senators. Representatives are elected for two-year terms, senators for four-year terms.
