Created by Peter Foott and filmed and set in Cork, Ireland, The Young Offenders tells the coming-of-age adventures of teenagers Conor (Alex Murphy) and Jock (Chris Walley) and their mother/guardian Mairead (Hilary Rose) as she tries to keep them on the straight and narrow.
The episodes follow the best friends as they navigate their awkward later teenage years, hatching plans and adventures to help distract from their tough home lives and their inability to stay out of trouble.
Series 2 was launched on BBC iPlayer earlier this month as a box set, and the BBC says it has had an "amazing" 4.1 million requests so far. The latest series is also currently being shown on BBC One on Monday nights.
Peter Foott comments: "We are so grateful to BBC Three and thrilled that they had such faith in the stories and characters of The Young Offenders that they commissioned a third series from us. We had a lot of fun filming Series 2 and 3 back to back over the summer in Cork, and we can't wait for everyone to see more of Conor, Jock, Mairead and all the characters next year in our third series.
"We've been amazed at the huge reaction to Series 2 so far, and we're so happy that we can officially announce that there's more on the way for fans of the show."
Kate Daughton, Head of BBC Comedy, says: "Young Offenders is spit-your-tea out funny and heartbreakingly emotional. A rare combination that's testament to the talents and passion of a very special cast, crew and writing team, led by creator and show-runner Peter Foott. We can't wait to share Series 3 - Cork's finest have never looked finer."
Fiona Campbell, Controller of BBC Three, says: "At BBC Three, we love championing local voices and The Young Offenders are a brilliant success story for us. With great characters and on-point writing that is hugely relatable to our audience, we're delighted they're coming back for another series."
