Balm is an unincorporated census-designated place in Hillsborough County, Florida, United States. The population was 1,457 at the 2010 census.

A post office was established here in 1902 and called "Doric"; it was renamed the next month to "Balm". The community was so named on account of their "balmy" air. Prior to 1902, the Seaboard Air Line Railway established Balm as a flag stop. The railroad built a one-room station and water tank. This made Balm a focal point, and a small community including a blacksmith, sawmills, a teacher, and a general store sprang up by 1911. In 1937, electricity arrived, soon followed by a community telephone, set up in a barn for all to use. By 1945 the area had a population of over a thousand.

Balm is located in southern Hillsborough County, bordered by Riverview to the north, Apollo Beach to the west, Sun City Center to the southwest, and Wimauma to the south.
