The great argus pheasant (Argusianus argus) is a species of pheasant. The scientific name of the Great Argus was given in reference to the many eyes-like pattern on its wings. Argus is a hundred-eyed giant in Greek mythology. The great argus is native to the jungles of Borneo, Sumatra and the Malay Peninsula in southeast Asia.

The double-banded argus, Argusianus bipunctatus, was long considered a potential second species of argus pheasant which is known only from the portion of a single primary flight feather. It was described in 1871 from this feather piece, found in a millinery shipment imported to London. Its origin was hypothesized to be from Java, Indonesia or Tioman Island of Malaysia, because of the great argus' absence from these locations. Parkes (1992) vehemently rejected the "species" validity and argued that the double-banded argus almost certainly represents a mutant form of the great argus.
