Pansy Bayou, covering 62 acres, is a bay situated in Sarasota County.

Between City Island and Lido Key, the bayou is rich in seagrass and manatees. A refuge has been established to ensure a place for these protected marine mammals to eat and rest. The bayou prohibits any entry by the public, except for neighboring homeowners. An exemption from the protective slow-speed zone in adjacent waters was allowed for the Ski-A-Rees water-skiing club who post manatee spotters during shows and practices. This bayou is included in the Sarasota Bay Estuary Program, is an Outstanding Florida Water, and is a SWFWMD SWIM waterbody.
