新蛙亚目（Neobatrachia）是无尾目下的一个亚目，而无尾目是蛙和蟾蜍所属的目。这个亚目的动物是无尾目中最高等的，并在无尾目下仍然存活的的一个分支，从命名来看，“Neobatrachia”逐字亦为“新蛙”（命名来自希腊语，“neo”意为“新”，“batrachia”意为蛙）。也是到目前为止三个亚目中物种数目最大的，超过5000种不同的物种，共计超过96%的无尾目都属于新蛙亚目。

始蛙亚目、中蛙亚目和新蛙亚目的不同主要基于解剖学上的不同，特别系骨骼的结构，还有一些外表的特征和行为的不同。

The Neobatrachia are a suborder of the Anura, the order of frogs and toads.

This suborder is the most advanced and apomorphic of the three anuran orders alive today, hence its name, which literally means "new frogs" (from the hellenic words neo, meaning "new" and batrachia, meaning "frogs"). It is also by far the largest of the three; its more than 5,000 different species make up over 96% of all living anurans.
