Gumbo Limbo Environmental Complex, Environmental research center in Boca Raton, United States.

Gumbo Limbo Environmental Complex is a nature center and research facility situated on a barrier island between the Intracoastal Waterway and the Atlantic Ocean. The grounds include walking trails, indoor displays about wildlife, marine rehabilitation pools, and research areas where staff care for injured and ill animals.

The site was first described in 1870 as Boca Raton Hammock, a coastal hammock and saw palmetto ridge bordered by a freshwater sawgrass marsh. After the Florida East Coast Railway arrived in 1895 the marsh was known as the "Spanish River". When the Boca Raton Inlet was opened during the 1920s land boom, saltwater intrusion let mangroves displace the freshwater plants by the 1940s.

The name comes from the gumbo-limbo tree (Bursera simaruba), common on the grounds. Volunteers from the surrounding community help run the center and its events, including nighttime sea turtle nesting observations. Visitors can watch researchers from Florida Atlantic University at work and talk with them about sea turtle behavior and shark sensory perception.

The grounds are easy to explore on foot with marked trails and viewing platforms that do not require special fitness. Florida weather is hot and humid, so arriving early in the day and bringing water makes for a more comfortable visit.

The facility treats sea turtles suffering from Fibropapillomatosis, a disease that only a handful of Florida centers are equipped to handle. This specialized work makes it a crucial refuge for one of the area's most vulnerable species.
