Compass Bank is a financial services company with its principal place of business in Birmingham, Alabama. The Parent Company was organized in 1970 as "Central Bancshares of the South, Inc." and commenced business in late 1971 upon the acquisition of Central Bank & Trust Co. and State National Bank.

The Company subsequently acquired substantially all of the outstanding stock of additional banks located in Alabama, 11 of which were merged in late 1981 to create Central Bank of the South, Alabama's first statewide bank. In November 1993, the Parent Company changed its name from "Central Bancshares of the South, Inc." to "Compass Bancshares, Inc.", and Central Bank of the South, the Company's lead bank subsidiary, changed its name to "Compass Bank."
