The Brazilian had been heavily linked with a move to Liverpool in recent weeks, but he has now decided to extend his stay in Spain.
"I am very happy with this deal after fighting for a long time to win the affection of the fans, my teammates and people inside the club," Costa told Atletico's official website.
Costa scored 12 goals in all competitions last season.
