胼足亚目（学名：Tylopoda）是偶蹄目的一个演化支，大约在4620万年前始新世中期开始出现，在北美洲及欧洲都有长期的化石记录，现在仅有骆驼科一支存活至今，目前分布在南美洲、亚洲及非洲北部；澳洲大陆也有由人类引进的野化骆驼分布。

胼足动物曾经非常多样化，比如原角鹿科、无防兽科、双锥齿兽科、剑齿兽科等都被归类于此亚目，高齿羊类的岳齿兽科及Agriochoeridae也包含在其中。

Tylopoda (meaning "swollen foot") is a suborder of terrestrial herbivorous even-toed ungulates belonging to the order Artiodactyla. They are found in the wild in their native ranges of South America and Asia, while Australian feral camels are introduced. The group has a long fossil history in North America and Europe. Tylopoda appeared during the Eocene around 46.2 million years ago.
