The Tickfaw River runs 113 mi from Amite County in southwest Mississippi to Livingston Parish in southeast Louisiana. Its mouth opens into Lake Maurepas, which conjoins with Lake Pontchartrain. The name Tickfaw (Tiak foha) is thought to be derived from the Choctaw phrase meaning "pine rest" or "Rest Among the Pines". More recent analysis however has determined the name to be derived from shortening and alteration of Pawticfaw meaning "place where wild animals have shed their hair".
