Iguania is the suborder of Squamata (snakes and lizards) that contains the iguanas, chameleons, agamids, and "New World lizards" such as anoles and Phrynosomatidae. The Iguania form the sister group to the remainder of the squamata. They are largely arboreal and have primitively fleshy, non-prehensile tongues, but this condition is obviously highly modified in the chameleons. This clade includes the following ^[1]:

• Family Agamidae – Agamid Lizards, Old World Arboreal Lizards
• Family Chamaeleonidae – Chameleons
• Family Corytophanidae – Helmet Lizards
• Family Crotaphytidae – Collared Lizards, Leopard Lizards
• Family Hoplocercidae – Dwarf and Spiny Tail Iguanas
• Family Iguanidae – American Arboreal Lizards, Chuckwallas, Iguanas, Iguanids
• Family Opluridae – Malagasy Iguanas
• Family Phrynosomatidae – North American Spiny Lizards
• Family Polychrotidae – Anoles and kin
• Family Tropiduridae – Tropidurid Lizards
