Oppeliinae is a subfamily within the Oppeliidae, a family of Jurassic ammonites characterized by forms that are mainly oxyconic, compressed with sharp venters, in the adult and with keeled inner whorls. Sutures are complex, consisting of a long series of evenly graded lobes and saddles with finely frilled endings.^[1]

The Oppeliinae gave rise to the Hecticoceratinae in the early Bathonian stage, near the middle of their range and to the , in the late Callovian, near the end of their tange, which in turn gave rise to the Streblitinae in the early Kimmeridgian and to the Haploceratidae in the late Kimmeridgian.^[2]

Distribution is worldwide, from the Middle Jurassic, except for Boreal regions.
