Atavism is the fifth studio album released by the American heavy metal band Slough Feg (formerly The Lord Weird Slough Feg).

A vinyl edition was also produced by Forest Moon Special Products in a limited print of 500.

The title of the album: atavism, is the tendency to revert to ancestral type.

In biology, an atavism is an evolutionary throwback, such as traits reappearing which had disappeared generations before.
