The Provisional Congress of the Confederate States, also known as the Provisional Congress of the Confederate States of America, was a unicameral congress of deputies and delegates called together from the Southern States which became the governing body of the Provisional Government of the Confederate States from February 4, 1861, to February 17, 1862. It sat in Montgomery, Alabama, until May 21, 1861, when it adjourned to meet in Richmond, Virginia, on July 20, 1861. In both cities, it met in the existing state capitols which it shared with the respective secessionist state legislatures. It added new members as other states seceded from the Union and directed the election on November 6, 1861, at which a permanent government was elected.

The Confederate States of America (CSA), commonly referred to as the Confederate States (C.S.), the Confederacy, or the South, was an unrecognized breakaway republic in the Southern United States that existed from February 8, 1861, to May 9, 1865.
