The renewal comes two weeks before the second half of season 4 resumes on the cable network. The fifth season is composed of 16-episodes and will premiere sometime next year.
"No other series on television travels the globe to tell a story like 'Covert Affairs,' and we are pleased to bring it back for another season," network head Chris McCumber says. "The series continues to be a cornerstone in our lineup."
Covert Affairs which stars Piper Perabo ranked as one of the top 10 cable scripted series, averaging 4 million viewers in the first half of its current season.
The show's fourth season resumes on Thursday, Oct. 17.
