Swayzee is a town in Sims Township, Grant County, Indiana, United States. The population was 952 at the 2006 census. Pipe Creek Sinkhole, uncovered in 1996 at the Pipe Creek Junior limestone quarry near Swayzee, has been the site of important paleontological discoveries dating from the Pliocene epoch. On its welcome sign, Swayzee claims to be "the only Swayzee in the world. " This motto is based on a story about a postcard sent by a serviceman overseas during World War II, which although being addressed only to "Swayzee", with no mention of Indiana or any other information, was still said to have been successfully delivered.
