Barbara "Babs" Jansen is one of the antagonists in the movie National Lampoon's Animal House.

Babs is a snobby sorority girl who finds Delta House repulsive and is in love with Greg Marmalard.  She lies about Greg's girlfriend Mandy having an affair with one of the Deltas so that she can have Greg to herself.  This leads to Greg and the rest of the Omegas beating said Delta (Otter) up.  After being indecently exposed when the Deltas crash the homecoming parade, she goes on to become a Hollywood tour guide.
