Lyons Bay, covering 109 acres, is a bay situated in Sarasota County, with the associated WBID(s): 2002A.

A small, suburban watershed, containing no named creeks, contributes little fresh water to this small, shallow estuary in the communities of Laurel and Nokomis. The adjacent Venice Inlet provides ample tidal flushing. Lyons Bay is legally protected from degradation by its status as an Outstanding Florida Water. Manatees occupy the bay on a regular basis.
