Batrachia is a clade of amphibians that includes frogs and salamanders, as well as the extinct allocaudates, but not caecilians. The name Batrachia was first used by French zoologist Pierre André Latreille in 1800 to refer to frogs, but has more recently been defined in a phylogenetic sense as a node-based taxon that includes the last common ancestor of frogs and salamanders and all of its descendants.
