A trailer hitch cover includes a removable hollow housing and a latch for securing the enclosure to the hitch so that it will remain in place while it is installed on the hitch. The hollow housing has an enclosed body and a tubular neck connected to and protruding from one wall of the enclosed body and being open at its outer end. The neck has a cross sectional size substantially smaller than that of the body. The enclosed body is formed by a pair of identical halves hinged together. Mating parts of the latch are mounted to identical halves of the tubular neck. The halves of the hitch cover are thus releasably secured together in a clam-shell fashion over the hitch so as to be mounted to a portion of the hitch at only the hollow neck of the housing.
