Showtime has canceled United States of Tara after three seasons on the air. Currently in its third season, the Diablo Cody-created comedy has four episodes remaining, with its series finale scheduled for June 20.

On the air since 2009, the series was a solid performer for the network in its early goings. Ratings unfortunately started to fall over the course of its run, with this current season's debut being watched by 411,000 viewers compared to 816,000 for last season's premiere.

The bad news comes on the heels of Showtime renewing series Nurse Jackie, which will return for a fourth season.
