Bithlo is a census-designated place and an unincorporated community in Orange County, Florida, United States. The population was 8,268 at the 2010 census, up from 4,626 at the 2000 census. It is part of the Orlando–Kissimmee Metropolitan Statistical Area.

The Bithlo Post Office opened in 1922. For 20 years in the early 20th century, Bithlo was an incorporated town, but in 1929 ceased to function as a town due to economic hardship. By 1941, the town council meetings had ended and in 1944 the Okeechobee Railroad Branch was abandoned. After the end of World War II, the town became known as a waste dump and pollution site. It was in 1970 when the residents of Bithlo petitioned the state legislature to revoke the town's charter. The city was finally unincorporated in 1977, an act which was not finalized until 1982 due to outstanding bonds and legal problems.

Bithlo is the location of several of the broadcasting towers for the digital television stations in the Orlando-Daytona Beach-Melbourne market. It is also home to Bithlo Park and the East Orange Babe Ruth youth baseball and softball program, one of the premier youth baseball and softball programs in Central Florida.

"Bithlo" derives from the Muskogee word pilo ("canoe"). The ⟨l⟩ represents a lateral fricative /ɬ/ which was often transcribed ⟨thl⟩. The unaspirated /p/ of Muskogee is acoustically as similar to English voiced and unaspirated /b/ as to English voiceless and aspirated /pʰ/.
