Atoka (/əˈtoʊkə/) is a local government area with a town charter in Tipton County, Tennessee, United States.

The population was 10,008 at the 2020 census, making the Town of Atoka the largest municipality in Tipton County.

Historians and genealogists can trace the Town of Atoka's origins back to the 1838 charter of Portersville.

Today not a store or store building remains in Portersville and it passes into history...[8] A peek into the life of John McLaughlin, a citizen of both towns, gives us some idea of what Portersville and Atoka were like: Our subject received a collegiate education at Bellenyna College, Ireland and in 1852 came to America, landing at Charleston, S. C.; then immediately went to Chester, S. C., and spent three years learning the carriage-maker's trade, when he moved to Aberdeen, Miss., and established a factory of his own, and three years later moved to Portersville, Tipton County, and continued the business five years, then went into merchandising and farming, selling goods at Portersville two years, then moved to Atoka and continued the mercantile business over ten years, and since that time has given his attention exclusively to farming and running a steam cotton-gin, which he owns.

[9]If the dates are taken into account, "the coming of the railroad in 1872" and "the name of Portersville changed to Atoka in 1875".

The official stance of the United States Postal Service, according to an article published by the Historian of the United States Postal Service in April 2008, is that Atoka was the first post office with rural free delivery in Tennessee starting on January 11, 1897.

At that time the United States Post Office Department was experimenting with rural routes.

Today there are two rural routes reaching out from the town, serving that section from the Mississippi river on the west to Salem on the east.

All mail for Munford, Drummonds, Richardson's Landing, Randolph and other communities passes through the post office at Atoka, whose postmaster is E. M. Quisenberry and whose rural carriers are J. E. McQuiston and R. S.
