Rhizostoma pulmo, commonly known as the barrel jellyfish, the dustbin-lid jellyfish or the frilly-mouthed jellyfish, is a scyphomedusa in the family Rhizostomatidae. It is found in the northeast Atlantic, and in the Adriatic, Mediterranean Sea, Black Sea and Sea of Azov. It is also known from the southern Atlantic off the western South African coast and into False Bay.

It is common in the Irish Sea. It typically is up to 40 cm (16 in) in diameter, but can exceptionally reach 90 cm (35 in), making it the largest jellyfish in British waters (Cyanea capillata reaches an even larger size, but is generally smaller in Britain).

It is a favourite food of the leatherback turtle.
