The Florida banded water snake (Nerodia fasciata pictiventris), a subspecies of the banded water snake (southern water snake - Nerodia fasciata), is a nonvenomous natricine colubrid native to the southeastern United States.

The Florida banded water snake is endemic throughout Florida, South Carolina, southwestern and southeastern North Augusta, Beech Island, South West of Aiken County including areas running alongside Savannah River, Northern Georgia.

[3] Dorsally, it is light brown or yellowish, with 26–35 reddish-brown to black crossbands.

In large adult individuals, the ground color on the lower sides is sometimes darker than the crossbands, producing an appearance of alternating blotches on the back and sides.

Mating occurs from March to May, and the young are born from May to August, in broods of 25–57.
