Happy Endings is an American television sitcom that aired on ABC from April 13, 2011, to May 3, 2013. The single-camera ensemble comedy originally aired as a mid-season replacement. The show was created by David Caspe. Caspe and Jonathan Groff served as the show's executive producer and showrunner.

On May 10, 2013, Happy Endings was canceled by ABC after three seasons. ABC's erratic scheduling of the third season, the season's lower ratings and subsequent cancellation, was called one of the "worst TV decisions" of the 2012–13 television season by the pop-culture website Vulture.

Happy Endings follows the dysfunctional adventures of six best friends living in Chicago: "crazy-in-love" married couple, businessman overachiever Brad (Damon Wayans Jr.) and his neurotic perfectionist wife Jane (Eliza Coupe); ditzy Alex (Elisha Cuthbert), a happy-go-lucky boutique owner and Jane's younger sister; daydreamer Dave (Zachary Knighton), an aspiring restaurateur and food truck owner; slacker manchild Max (Adam Pally), who struggles to hold a job and maintain a consistent relationship; and outgoing party girl Penny (Casey Wilson), a serial dater on an eternal search for Mr. Right.

The series begins with the wedding of Dave and Alex, which comes to an abrupt halt when Alex leaves Dave at the altar. The six friends must cope with a sudden change in the group dynamic as Dave and Alex mourn their relationship and the rest of the group try to preserve their friendship. Dave and Alex decide to stay friends, but there are many more complications down the road.

While the initial premise of Dave and Alex's broken engagement was the focal point in earlier episodes, this premise was mostly abandoned as the series went on. Instead, the focus shifted to the group dynamic of six best friends, in a similar vein of ensemble comedies like Friends and How I Met Your Mother. Each episode typically features two plot lines in which varying combinations of the six characters are involved.

On January 19, 2010, ABC green-lit the pilot episode, which was written by David Caspe and directed by Anthony Russo and Joe Russo. The show is from production companies Sony Pictures Television, ABC Studios, and executive producer Jamie Tarses' FanFare Productions. Executive producers are Jamie Tarses, Jonathan Groff, and The Russo Brothers.

Casting announcements began in February 2010, with Damon Wayans Jr. first cast as Brad, Jane's husband who does whatever she says. Next to join the series was Casey Wilson as Penny, the group's desperate and single friend. Eliza Coupe and Adam Pally shortly joined that cast, with Coupe playing Jane, Alex's control freak sister who is married to Brad, and Pally playing Max, Dave's close friend and roommate. Elisha Cuthbert later joined the cast as Alex, Dave's ex-fiancée who leaves him at the altar. Zachary Knighton was last actor to be cast as the newly single Dave.

The pilot was ordered to series on May 13, 2010, as a mid-season entry in the 2010–11 United States network television schedule.
