Joice Island is a small island in Grizzly Bay (part of Suisun Bay) in California. It is part of Suisun Marsh, and has been used for hunting since the late 19th century. After a failed attempt to reclaim the land for asparagus and alfalfa farming in the early 1900s, Joice Island spent several decades as a wildlife refuge before being opened to the public for hunting in 1964. Currently, the upper portion of Joice Island is part of the California Department of Fish and Wildlife's Grizzly Island Wildlife Area; fishing, as well as the hunting of waterfowl and pigs, is permitted there on a limited basis.
