An ostomy closure is disclosed for sealing an ostomy pouch after use and removal from an ostomy mounting plate. The ostomy mounting plate is secured to an individual. The ostomy closure comprises a cap body defining an interior surface and an exterior surface extending to a peripheral edge. A cap flange is coupled to the peripheral edge of the cap body and extends from the interior surface of the cap body. A cap locking member is integral to the cap flange. A cap lip defining an interior surface and an exterior surface extends from the cap flange for manipulating the cap body and the cap flange. The cap flange couples with a pouch flange of the ostomy pouch for defining a sealing closure for maintaining the stool and the stool odor within the ostomy chamber and a locking closure for preventing inadvertent removal of the cap flange from the pouch flange.
