Sepiida is an order of ten-armed cephalopods containing a single suborder, Sepiina. This suborder contains the following superfamilies and families: ^[2]

Taxonomy

• Order Sepiida
  • Suborder Sepiina
    • Superfamily Sepioidea
      • Family † Anomalosaepiidae Yancey & Garvie, 2011
      • Family † Belosaepiidae Dixon, 1850
      • Family Sepiidae W.E. Leach, 1817
    • Superfamily †Vasseurioidea ^[3]
      • Family † Vasseuriidae
      • Family † Belosepiellidae

The bobtail or bottletail squid (order Sepiolida) were previously placed within this order, but they are now understood to form their own distinct order; ^[2] their exact relationship with the cuttlefish is currently in flux, but they have not been recovered close to Sepiida in recent phylogenetic analyses (see Decapodiformes#Taxonomy).
