The show is Syfy's biggest hit with women and its most recent episode was watched by about 1.5 million viewers.
"With the success of season two, 'Being Human' has become a premier destination for Syfy viewers," Mark Stern, president of original content at Syfy, said in a statement. "Jeremy Carver and Anna Fricke have taken this series to new heights this year and we're excited to see where the third season will go."
The show follows three roommates in Boston -- vampire Aidan (Sam Witwer), ghost Sally (Meaghan Rath) and werewolf Josh (Sam Huntington) -- as they struggle to keep their secrets and live life as normal as possible. "Supernatural" veteran Jeremy Carver serves as the co-showrunner along with "Everwood's" Anna Fricke on "Being Human," which is based on the UK hit of the same name.
"Being Human" airs Mondays at 9 p.m. EST on Syfy.
