The teen comedy-drama starring Ashley Rickards will see its upcoming third run almost doubled from 12 to 20 episodes, according to The Hollywood Reporter.
"[Creator] Lauren Iungerich's creative vision, coupled with this extraordinarily talented cast, make Awkward the perfect series for MTV," MTV head of programming David Janollari said.
"Critics and our audience alike have fallen in love with Awkward, and we're thrilled to bring this terrific series back for a third, supersized season."
The series has risen 6% year-on-year and ranks as the number one show in its timeslot for women and teens aged 12-34.
MTV have also renewed Teen Wolf for a third season, while new scripted shows include the US remake of The Inbetweeners and comedy drama Underemployed.
Awkward continues tomorrow (July 26) at 10.30pm on MTV.
