披毛目（学名：Pilosa）是胎盘类哺乳动物下的一个目，现有物种仅分布于美洲，包括了食蚁兽、树懒及已灭绝的地懒。在异关节总目（或贫齿总目）未被提升为总目前而常称作「贫齿目」的时候，披毛目也常称作「披毛亚目」。

此目的起源可追溯至古近纪（约60万年前，仅在中新代稍后的一段时间）。原生于南美洲，后因南北美洲生物大迁徙而在北美洲也有分布。 一直以来，披毛目及有甲目等都被分类在「贫齿目」下，但近年普遍已将贫齿目提升为总目（即异关节总目），而将早前的两个亚目提升到目的层次。这是因为贫齿目过去是将没有牙齿的哺乳动物放在一起，但实际上这些成员却是一个多系群。

The order Pilosa is a group of placental mammals, extant today only in the Americas. It includes the anteaters and sloths, including the extinct ground sloths, which became extinct about 10,000 years ago. The name comes from the Latin word for "hairy". Pilosans are good examples of ecological harmony. Anteaters, for example, feed lightly and for a short time at any one ant nest, allowing the colony to regrow easily. Also, sloths' fur is home to many insects, as well as a type of algae that helps camouflage the sloths.
