Back to the Known is the second EP released by American punk rock band Bad Religion.

The name of the EP is a reference to the band abandoning the progressive rock influences of its previous album, 1983's Into the Unknown, and returning to its punk roots.

During a live show in the mid 1980s, they played the song twice in a row at a sped-up pace the second time.

Due to a typo on a number of internet sources and the back cover of the vinyl, many believe that the EP was released in 1984, but this appears to be false.

According to a Bad Religion fan site, the EP was recorded in 1985 with then-former and now-current guitarist Brett Gurewitz producing it.
