The announcement was made Wednesday by Mark Stern, Syfy's president of original content and co-head of original content for Universal Cable Productions.
Starring Sam Witwer, Meaghan Rath, Sam Huntington and Kristen Hager, the supernatural show's Season 3 finale aired Monday.
"'Being Human' really hit its stride creatively this year," said Stern in a statement. "This show has become a signature series for Syfy and we are thrilled to have it return in 2014."
The show is about a vampire, ghost and werewolf who are roommates.
