Deveaux Bank is a horseshoe-shaped sand spit island encompassing a 215-acre (87-hectare) bird sanctuary at the mouth of the North Edisto River in Charleston County, South Carolina.

During World War II, Deveaux Bank was used as a bombing range.

The bank was completely submerged by Hurricane David in 1979 and tidal shifts that followed the next spring.

[3] Over the next several years the island continued to rebuild as sand was deposited by currents.

Due to a lack of land predators, the island has become a heavily utilized bird nesting area.
