Legislative Assembly of the Territory of Colorado
The Legislative Assembly of the Territory of Colorado did not number its legislatures; rather, it numbered its sessions, which occurred occasionally from 1861 to 1876.

1865 Territorial Legislature
For a brief time in 1865, Colorado had an approved state constitution, and selected a legislature and other elected officials. The legislature briefly convened, believing that their statehood had been approved. However, Andrew Johnson vetoed the corresponding enabling act, and the body that met as the state legislature was disbanded. This legislature met from December 12 through December 19, 1865.

General Assembly of the State of Colorado
The state legislature has met in Denver, Colorado since its founding.
