Petticoat Junction is an American situation comedy produced by Filmways, which originally aired on the CBS network from 1963 to 1970. The rights to the show are held by CBS Paramount Domestic Television. The setting for the series was the Shady Rest Hotel in the farming town of Hooterville.

A petticoat is a garment worn under a woman's skirt. The opening titles of the series featured a display of petticoats hanging on the side of a large water tank. The "junction" in the title indicates that the Shady Rest Hotel was situated at a crossing of two train lines (though only one is ever mentioned).
