逆断层英语:reverse faultthrust fault),是断层的一种,其断层上盘的岩体相对于下盘,往上移动,原来位置较低的地层会移动到位置较高地层的上方,因此较老的地层会出现在较新地层的上方。逆断层一般都是因为压缩力所造成。

断层上盘推移较远,与原地基岩不是一个整体,属外来岩体,称为推覆体。

逆冲断层(thrust)则为角度较小的断层

A thrust fault is a type of fault, or break in the Earth's crust across which there has been relative movement, in which rocks of lower stratigraphic position are pushed up and over higher strata. They are often recognized because they place older rocks above younger. Thrust faults are the result of compressional forces.
