'Behave Yourself' is the seventh EP by the American indie rock band Cold War Kids.

The EP was announced on their official website on October 26, 2009.

The EP's artwork reads "These songs were recorded some time between "Loyalty" and now.

They didn't belong there but kept hanging around, started trouble, made friends, and insisted they be heard".

"Sermons" is a re-recording of the track "Sermons vs. the Gospel" that initially appeared on the With Our Wallets Full EP and as a hidden track at the end of their full-length debut Robbers & Cowards.
