Six Degrees (or 6˚, stylized as SIX DEGREES) is an American drama television series about six residents of New York City and their respective relationships and connections with one another, based on the idea of six degrees of separation.

It premiered on September 21, 2006, after Grey's Anatomy on ABC. The show was created by Raven Metzner and Stuart Zicherman. J. J. Abrams, Bryan Burk and Thom Sherman serve as executive producers through their Bad Robot banner. The pilot episode was directed by Rodrigo García. It was filmed on location in Manhattan and at Silvercup Studios in Long Island City, Queens, New York. The show's theme song, "Here Comes Now", was written and performed by Jakob Dylan.

The series was shown in Canada on Global on Wednesday evenings prior to the American airings. It made its United Kingdom debut on ITV on May 28, 2008, where all thirteen episodes were aired.

On November 8, 2006, Six Degrees was pulled off the schedule by ABC due to a decrease in ratings. By January 2007, ABC had not ordered any more episodes to be produced for the season.

The series returned on March 23, 2007, with its seventh episode in a new timeslot at 9:00pm EDT on Fridays and with Josh Charles added to the cast. After just two weeks back on the air, the series was pulled by ABC for a second time due to poor ratings, on April 2, 2007, further fueling doubts of the series continuing. On April 27, 2007, the unaired ninth episode was posted on ABC's website, with the last four weekly after.

On May 15, 2007, the series was canceled by ABC. In June 2007, ABC's programming calendar available to the media indicated the final episodes of the series would be broadcast beginning Friday, August 10, 2007; however, ABC decided instead to air repeats of another show.
