Production on the final 12 episodes of the show is to begin early next year. The eighth season is scheduled to premiere in June.
"Homeland has been a game-changing series for Showtime, as provocative about the world we live in as it is prescient," David Nevins, president and chief executive officer of Showtime Networks Inc., said in a statement Monday.
He added: "This project, arriving right at the beginning of my Showtime tenure thanks to Alex Gansa and Howard Gordon, and brought to life by a remarkable cast led by Claire Danes and Mandy Patinkin, is a richly written character study that is now ready for its natural conclusion. Viewers will be rewarded by the way Alex brings Homeland home."
Patinkin is up for a Best Supporting Actor in a Drama Emmy for his work on the show.
The cable network announced last month that it is wrapping up another long-running show -- The Affair -- with its upcoming fifth season.
