Osteolepiformes, also known as Osteolepidida, is a group of prehistoric lobe-finned fishes which first appeared during the Devonian period. The order contains the families Canowindridae, Megalichthyidae, Osteolepididae and Tristichopteridae, in addition to several monotypic families. The order is generally considered to be paraphyletic because the characters that define it are mainly attributes of stem tetrapodomorphs.
The following taxonomy is based on Borgen & Nakrem, 2016:

Order †Osteolepiformes
Suborder †Osteolepidoidei
Family †Osteolepididae
Family †Thursiidae
Family †Megalichthyidae
Suborder †Cyclolepidoidei

Family Panderichthyidae (incl. Elpistostegalia)
Family †Tristichopteridae
Superfamily †Parapodoidea
Family †Canowindridae
Family †Medoevididae
Superfamily †Rhizodontoidea
