The Iowa General Assembly is the legislative branch of the state government of Iowa. Like the federal United States Congress, the General Assembly is a bicameral body, composed of the upper house Iowa Senate and the lower Iowa House of Representatives respectively. The Senate consists of four year terms and the House consists of two year terms. The General Assembly convenes within the Iowa State Capitol in Des Moines since the capital was moved there in 1857.[1] The assembly convenes annually on the second Monday in January.[2]


The Iowa General Assembly consists of 50 senators and 100 representatives. Each senator represents about 63,848 people and each representative about 31,924 people as of the 2020 United States census.[3] The current legislative maps were enacted on November 4th, 2021[4] for the 2022 elections and the 90th General Assembly.

Leaders in the Senate are President Amy Sinclair (R), and President Pro Tempore Brad Zaun (R). Partisan Senate leadership includes Majority Leader Jack Whitver (R), and Democratic Leader Pam Jochum (D). In the House, the Speaker is Pat Grassley (R), and the Speaker Pro Tempore John Wills (R). Partisan House leadership includes Majority Leader Matt Windschitl (R), and Minority Leader Jennifer Konfrst (D).[5] The Republican Party currently holds a 2/3rds super-majority in the Senate.
