Gekkoninae is a diverse subfamily of the family Gekkonidae, geckos. It has the most species and genera — over 850 species in 30 genera. Hemidactylus and Cyrtodactylus together account for 185 species.

The Emydinae are a subfamily of turtles in the family Emydidae.

Alligatorinae is a subfamily within the family Alligatoridae that contains the alligators and their closest extinct relatives, and is the sister taxon to Caimaninae (the caimans). Many genera in Alligatorinae are described, but only the genus Alligator is extant, with the remaining being extinct.

Uromastycinae is a subfamily of reptiles in the family Agamidae.

The Draconinae are a subfamily of reptiles in the family Agamidae found in southern Asia and Oceania. Some taxonomists believe these genera belong to the subfamily Agaminae.

Chamaeleoninae is the nominotypical subfamily of chameleons (family Chamaeleonidae). The Family Chamaeleonidae was divided into two subfamilies, Brookesiinae and Chamaeleoninae, by Klaver and Böhme in 1986. Since its erection in 1986, however, the validity of this subfamily designation has been the subject of much debate, although most phylogenetic studies support the notion that the pygmy chameleons of the subfamily Brookesiinae are not a monophyletic group. While some authorities have previously preferred to use the subfamilial classification on the basis of the absence of evidence principal

The Trionychinae are a subfamily of turtles in the family Trionychidae.

The Family Chamaeleonidae was divided into two subfamilies, Brookesiinae and Chamaeleoninae, by Klaver and Böhme in 1986. Under this classification, Brookesiinae included the genera Brookesia and Rhampholeon, as well as the genera later split off from them (Palleon and Rieppeleon). The Brookesiinae are small, often brown in colour, and occur in central Africa and Madagascar. They have terrestrial habits, or may be found in the lower levels of shrubs. Since its erection in 1986, however, the validity of this subfamily designation has been the subject of much debate, although most phylogenetic s

Cyclanorbinae, also known commonly as the flapshell turtles, is a subfamily of softshell turtles in the family Trionychidae. The subfamily is native to Africa and Asia.

Acontinae is a subfamily of limbless skinks within the family Scincidae.

Mabuyinae is a subfamily of lizards, commonly known as skinks, within the family Scincidae. The genera in this subfamily were previously found to belong the Mabuya group in the large subfamily Lygosominae.

Crocodylinae is a subfamily of true crocodiles within the family Crocodylidae, and is the sister taxon to Osteolaeminae (dwarf crocodiles and slender-snouted crocodiles).

Gavialinae is a subfamily of large semiaquatic crocodilian reptiles, resembling crocodiles, but with much thinner snouts. Gavialinae is one of the two major subfamilies within the family Gavialidae - the other being the subfamily Tomistominae, which contains the false gharial and extinct relatives.
