Nokomis is an unincorporated town along the Gulf Coast of Florida, United States, located south of Osprey and just north of Venice. The town has access to the coast through Nokomis Public Beach and Casey Key. The town's population was 3,167 at the 2010 census. It is part of the Bradenton–Sarasota–Venice Metropolitan Statistical Area.
Nokomis includes approximately 2.5 miles of the Legacy Trail, including a water crossing at the Shakett Creek (Dona Bay) bridge.
Casey Key is a barrier island to the northwest of the CDP along the Gulf of Mexico, where there are luxurious beachfront houses lining the key. Casey Key is not part of any CDP.
In 1917, Alfred F. Wrede established the first post office with the name of Nokomis southwest of the original Venice post office. The same year, orthopedic surgeon Dr. Fred Albee purchased 112 acres from the Sarasota-Venice Company. With Ellis W. Nash,Albee created the Nokomis subdivision by subdividing the property into 130 lots, with streets radiating from two inner avenue circles and the new asphalt highway, which eventually became U.S. 41.
