Bibb County is located to the south and southwest of Jefferson County and is part of the 7-county Birmingham-Hoover Metropolitan Statistical Area. It is bordered by Tuscaloosa, Jefferson and Shelby County to the north, by Hale County to the west, Perry County to the south, and Chilton County to the east.
The present Bibb County was originally part of a sprawling Monroe County, designated by the Mississippi territorial legislature in 1815, which stretched into what is now central Alabama from the Mobile delta. In 1817 it became part of Montgomery County, which was ceded into the Alabama Territory by 1818. The northern section was split off as Cahawba County (named for the Cahaba River) on February 7 of that year. In 1820 it was renamed in honor of William Wyatt Bibb, the first Governor of Alabama, who had died in office the preceding summer.
The first seat of Bibb County was a temporary location at Falls of the Cahaba, which was used from 1819 to 1822, when it was moved to a community surrounding a sawmill, which was given the name Bibb Court House. In 1829, the seat was moved to Centreville Court House, since shortened to Centreville. The Bibb County Commission meets twice monthly in the 1902 Bibb County Courthouse. The acting Sheriff is Downey McGee. Public schools in Bibb County are run by the Bibb County Public School District.
