The announcement was made Monday by Bob DeBitetto, president and general manager of A&E Network and BIO Channel.
Season 1 of the show premiered in July. Season 2 of "The Glades" will begin pre-production later this year on 13 new episodes slated to premiere in 2011, the network said.
"'The Glades' has garnered critical acclaim and a loyal audience in its first season," DeBitetto said in a statement. "With superb writing and exceptional acting, led by a standout performance by Matt Passmore, we're pleased that the series has struck a chord with fans."
