"Pretty Little Liars has taken its place in the zeitgeist and reigns supreme in pop culture," said ABC Family president Tom Ascheim. "I am glad to bring another two seasons to our audience because 'A' has a lot in store for our Liars."
The sixth season is set to debut in mid-2015, while the seventh season is expected to bow in mid-2016.
The show, which holds the record as the most-tweeted scripted-series telecast of all time, is the No. 1 series in the history of ABC Family.
The season five premiere called EscApe From New York picks up with Aria and the Liars reeling from Ezra's shooting at the hands of "A." Be sure to catch the season premiere tonight at 8 ET/PT.
