WSTU (1450 kHz) is a commercial AM radio station licensed to Stuart, Florida, and serving the Treasure Coast.

After a brief ownership by a Broward County businessman, it was sold to Barry Grant Marsh and David Pomerance.

When WSTU went on the air, Stuart went from the biggest city on Florida's east coast without its own radio station to the smallest city on Florida's east coast with its own radio station.

[citation needed] WSTU was also one of the first radio stations in Florida to broadcast high school sports on a regular basis and continues to broadcast high school football, basketball and baseball.

[2] For a period of time, WSTU (1450) AM radio station program schedule included a Saturday Night Dancing 'Bongo' Party from 7 p.m. to 11:30 p.m., hosted by Walter Oden.
