Penion maximus is a species of very large predatory sea snail or whelk, commonly known as giant whelk or great whelk, a marine gastropod mollusc in the family Buccinidae, the true whelks.
Penion maximus is the largest species of Penion siphon whelk, and is endemic to Australia. The species could be confused with the sympatric species P. mandarinus, however P. mandarinus is typically smaller and has a smoother shell with a shorter siphonal canal.
The range of the species extends from waters off Tasmania and Victoria to lower Queensland.
