Eurypholis (meaning "broad scale") is a genus of prehistoric marine aulopiform fish known from the Late Cretaceous (Cenomanian to Campanian). It contains three species, known from Europe, the Middle East, and east Asia. ^{[1] [2]}

The following species are known: ^{[1] [2] [3]}

• †E. boissieri Pictet, 1850 (type species) - Cenomanian of Lebanon (Sannine Formation) (=E. sulcidensPictet, 1850)
• †E. japonicusUyeno & Minakawa, 1983 - Campanian of Shikoku, Japan (Izumi Group) ^[4]
• †E. pulchellus(Woodward, 1901) - Cenomanian of England (English Chalk) (= Enchodus pulchellusWoodward, 1901) ^{[5] [6]}

Potential indeterminate remains are known from the Cenomanian of Uzbekistan and the Maastrichtian of Greece, though a review of the Greek records has found no evidence of these remains belonging to Eurypholis. ^{[2] [7]}

Of these species, E. boissieri is known from many complete, articulated skeletons, E. pulchellus is known from fragmentary specimens, and E. japonicus is known from a single mandible (closely resembling that of pulchellus) with very large attached teeth. ^{[1] [4] [5]}
