Orange Is The New Black has been renewed for three more seasons with Netflix on the condition Jenji Kohan remains at its helm.
The renewal is the longest commitment to any TV series in recent times and secures seasons five, six and seven of OITNB, according to Variety magazine.
Season four of the series, which is set in a female prison and is the most-watched show on the TV streaming service, concludes on June 17.
Kohan was ecstatic with the deal."Three more years! Not quite a political term, but still plenty of time to do some interesting things," she said in a statement.
"In some cultures, 'May you lead an interesting life', is a curse, but I don't live in those cultures. Here's to keeping it interesting. Thanks Netflix!"
She thanked her cast and crew as well as all the "mixers and shleppers with whom I have the pride and honour of crafting this show".
"Three more years! Three more years!" she added.
The renewal follows Saturday's SAG Awards in Los Angeles, at which OITNB took the comedy ensemble award for the second year in a row and the comedy actress trophy for star Uzo Aduba for the second straight year.
Netflix VP of original content Cindy Holland described the show as a "phenomenal and impactful series that is both funny and dramatic, outrageous and heartfelt".
"Audiences around the world have come to love the ladies and men of Orange Is The New Black, and we are eager to see where three more seasons will take them," she added.
