Vera, Scott & Bailey, Monroe and Case Sensitive will all be returning with new episodes, the channel announced today.
Vera, which stars Brenda Blethyn as a detective, will return with four two-hour films. Filming has already started on the new instalments.
Elsewhere, Scott & Bailey will return next year with eight new episodes. The drama stars Suranne Jones and Lesley Sharp as police officers working together in Manchester and picked up ratings of 5.77m for its finale earlier this month.
The new series of Monroe will focus on neurosurgeon Gabriel Monroe getting used to single life and facing further challenges at work.
James Nesbitt and Sarah Parish will return to the series, along with two "major new additions" to the cast. However, production on the show is not expected to begin until next year.
Meanwhile, Case Sensitive will return with a new two-part story based on Sophie Hannah's novel The Other Half Lives. Darren Boyd and Olivia Williams are due to reprise their roles as DC Simon Waterhouse and DS Charlie Zailer.
ITV's director of drama commissioning Laura Mackie said: "We couldn't be more delighted with the success of Vera, Case Sensitive, Monroe and Scott & Bailey. It's terrific to think we are commissioning the most watched and appreciated original dramas for the ITV1 audience."
ITV has already renewed its drama Kidnap & Ransom and is working on a new one-off film based on the work of Victorian detective Inspector Jack Whicher following the success of The Suspicions of Mr Whicher.
