Lake Jesup, Lake in Seminole County, Florida, US.

Lake Jesup is a large water body in Seminole County that covers roughly 16,000 acres of open water and marshland. It connects to the St. Johns River through several channels and wetland passages that flow naturally between the two systems.

The lake took its name from Brigadier General Thomas Jesup, who led military operations during the Second Seminole War in the 1800s. This naming reflects the conflict period that shaped the region's history.

The lake is named after Brigadier General Thomas Jesup, who served in the Second Seminole War. Around the water, small businesses run lakeside restaurants, fish camps and airboat tours. The Friends of Lake Jesup, a citizens' group, has monitored restoration projects such as the 1996 berm removal and the 2008 SR 46 bridge rebuilding.

The lake is accessible through multiple entry points that offer hiking, biking, boating, and wildlife observation opportunities. Different areas provide varying conditions and activity options depending on the season and water levels.

The lake hosts one of Florida's largest alligator populations, which visitors can observe in their natural setting. It also serves as a critical stopover for migratory birds during their seasonal journeys.
