Season   One   Two   Three   Four    

Season Four of Sanctuary is premiered on October 7th and concluded on December 30, 2011 on Syfy in the US and SPACE in Canada, and some time later in the United Kingdom on WATCH and on Syfy in Australia.

In describing what the fourth season would be about, Amanda Tapping stated that the Hollow Earth storyline would still be dealt with. She also requested that Magnus be given a love interest. At San Diego Comic-Con, Amanda Tapping and Robin Dunne stated that season four will contain a musical episode called 'Fugue'.

Starting with this season, the episodes are split into six "acts" instead of four, to afford an additional commercial break. Months after the fourth season ended, Syfy announced on May 21, 2012 that Sanctuary will not be returning for a fifth season and that the show is cancelled. Syfy cancels Sanctuary.
