壁虎下目（Gekkota）是有鳞目硬舌亚目的一个下目，包含所有的壁虎，与缺乏四肢的鳞足蜥。

Gekkota is an infraorder of squamate reptiles in the suborder Scleroglossa, comprising all geckos and the limbless "snake-lizards" of family Pygopodidae. The legless lizards of the family Dibamidae, also referred to as blind lizards, have occasionally been counted as gekkotans, but recent molecular phylogenies suggest otherwise.
