The following is the third part of a list of TV series that are ending or have been cancelled during the 2010-11 season.

For more, be sure to check out part one, part two, and part three of the listings.

Note: Go here for the latest 2011-12 season list.

Networks and cable channels have different ideas of when a season starts or ends but, to us, it makes sense to start the season on June 1, 2010 and and it on May 31, 2011. In some cases, the last episode of a show aired earlier than these dates but the network didn’t get around to canceling the series until later. If you don’t see what you’re looking for, try the 2008–2009 page, the 2009–2010 listings.
