The Texas Senate is the upper house of the Texas Legislature, with the Texas House of Representatives being the lower house. Together, they compose the state legislature of the state of Texas.

The Texas Legislature is the state legislature of the U.S. state of Texas. It is a bicameral body composed of a 31-member Senate and a 150-member House of Representatives. The state legislature meets at the Capitol in Austin. It is a powerful arm of the Texas government not only because of its power of the purse to control and direct the activities of state government and the strong constitutional connections between it and the Lieutenant Governor of Texas, but also due to Texas's plural executive.
