‘Grantchester’ season 10 release date, cast, plot, and more

Rishi Nair as Alphy Kotteram and Robson Green as Geordie Keating in 'Grantchester' season 10

Grantchester season 9 was an emotional rollercoaster for fans. Tom Brittney’s Will Davenport said goodbye to Grantchester, Geordie (Robson Green), and the rest of his friends for a new job elsewhere in the country, and soon enough, a new vicar rolled into town.

This vicar’s a little different, though. Charming, handsome, distrustful Alphy Kotterm (Rishi Nair) has no desire to work with the police to solve the various distressing murders in Grantchester and its surrounds—initially, at least. While that may make DI Keating’s job a little easier, we have no doubt these two will warm up to one another soon. Thankfully, Grantchester has been renewed for season 10, so we’ll get to learn more about their tentative friendship as the show moves on, full steam ahead.

Here’s everything we know about Grantchester season 10 so far.

Grantchester season 10 release date

PBS Masterpiece recently revealed the official release date for Grantchester season 10, and it’s sooner than you might think! For those of you in the U.S., get ready to visit the Cambridgeshire countryside this summer, as the new season premieres on Sunday, June 15, 2025. New episodes will be released weekly.

I’m afraid it will likely be a longer wait for those of us in the U.K., as Grantchester season 9 was only recently released on ITV. We might have to wait until early 2026 (I know, I know. It’s unfair).

Grantchester season 10 cast

Joining Robson Green and Rishi Nair for Grantchester season 10 are a few fan-favorite and familiar faces, including:

  • Al Weaver as Leonard Finch
  • Tessa Peake-Jones as Mrs. C
  • Kacey Ainsworth as Cathy Keating
  • Oliver Dimsdale as Daniel Marlowe
  • Nick Brimble as Jack Chapman
  • Bradley Hall as Larry Peters
  • Melissa Johns as Miss Scott

Grantchester season 10 plot

Though PBS hasn’t released episode-specific details yet, they have unveiled a teasing summary of what to expect in Grantchester season 10:

“In Grantchester season 10, as DI Geordie Keating (Robson Green) and Reverend Alphy Kottaram (Rishi Nair) continue to work together as a crime-solving duo in scenic Grantchester, they must also support each other through changing times, family struggles, and personal secrets. This season, Alphy feels like he’s found a home, but he’s forced to confront secrets he’s kept close to his chest. Will he be able to let anyone fully in, or must he confront truths about himself first?”

I am DYING to know Alphy’s secrets. This new season can’t come soon enough!
