The '''cloacal membrane''' is the membrane that covers the [[embryonic cloaca]] when still in the [[development of the urinary and reproductive organs]].
It is formed by [[ectoderm]] and [[endoderm]] coming into contact with each other. After separation of the cloaca into the urogenital and anal parts, the cloacal membrane, in turn, is separated into a [[urogenital membrane]] and an [[anal membrane]].
