Scombroidei or Scombrales is a suborder or infraorder of the order Scombriformes or suborder Scombroidei. The suborder or infraorder includes the tunas, mackerel and snake-mackerels. Regular scombrids are observed to have large heads, eyes, and mouths. In most cases, the second dorsal fin will develop before the development of the first.

The earliest known members of the group are unnamed members of Scombridae and Trichiuroidea from the Paleocene (Danian) strata from the Dakhla Formation (Egypt) and the scombrid Landanichthys from the Selandian of Angola, although potential fossil teeth of Eutrichiurides are slightly older.
