Albert Rust was an American politician and slaveholder, who served as a delegate from Arkansas to the Provisional Congress of the Confederate States from 1861 to 1862. A member of the Democratic Party, he was the U.S. representative from Arkansas's 2nd congressional district (1859–1861). He also served as a senior officer of the Confederate States Army who commanded infantry in the Eastern, Western, and Trans-Mississippi theaters of the American Civil War.

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.
