Galeta Island is an island located on the Atlantic side of the Republic of Panama, just east of the city of Colón, Panama.

Galeta Island was the site of a U.S. military communications facility from the 1930s through 2002, when it was turned over to the government of Panama. The facility included an operations building located in the center of a U.S. Navy AN/FRD-10A(V) antenna array, which is a Circularly Disposed Antenna Array (CDAA) also known as a Wullenweber array.

The island was shared with the Smithsonian Tropical Research Institute (STRI), which still maintains a research facility on the island. U.S. military activity ceased on the island after 2002, while tropical research continues in a separate facility located just east of the former communications facility.
