An ostomy closure is disclosed for sealing an ostomy pouch after use and removal from an ostomy mounting plate. The ostomy closure may comprise a flexible storage bag having a bag base and a bag opening and define a bag chamber. The bag base may couple to an exterior surface of the ostomy pouch. The bag opening may retract over the ostomy pouch and define a bag pouch enclosure for encapsulating the ostomy pouch within the bag chamber to prevent leakage of contents within the ostomy pouch from and through flexible storage bag upon being securely sealed at an opened end.
