Balm is an unincorporated census-designated place in Hillsborough County, Florida, United States.

[2] A post office was established here in 1902 and called "Doric"; it was renamed the next month to "Balm".

[5] Prior to 1902, the Seaboard Air Line Railway established Balm as a flag stop.

This made Balm a focal point, and a small community including a blacksmith, sawmills, a teacher, and a general store sprang up by 1911.

[6] 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.

U.S. Route 301 forms the western border of the Balm CDP, and leads north 12 miles (19 km) to the eastern outskirts of Tampa and southwest 28 miles (45 km) to Bradenton.

Originally a rail stop and logging town, the economy is mostly agricultural, particularly citrus.
