The 20th season of NCIS has been airing in the US for a few months now, but we're finally about to get the episodes here in the UK - and things are kicking off with a bang.

The new season starts with a crossover with NCIS: Hawai’i, while another crossover with NCIS: Los Angeles is also on the cards for later in the season.

NCIS season 19 saw one of the biggest shake-ups in its history after long-time star Mark Harmon, AKA Leroy Jethro Gibbs, left the show after the first five episodes.

But when do new episodes of the police procedural start airing in the UK? Read on for everything you need to know about NCIS season 20.

It has! The show was renewed for its incredible 20th season on 31st March 2022, along with the rest of the NCIS franchise, including NCIS: Hawai’i and NCIS: Los Angeles.

This means that the series is tied for the third-longest-running U.S. primetime drama series behind Law & Order: SVU and Law & Order.

It's official - we finally have a release date for NCIS season 20 in the UK.

Season 20 has been airing in the US since 19th September 2022, but we're finally about to get the episodes on this side of the pond, as they start streaming weekly on Disney Plus from Wednesday 18th January 2023.

NCIS cast: who will be back for season 20?

All the main stars from NCIS season 19 are set to return, including Gary Cole, Sean Murray and Katrina Law. Meanwhile, the show is also set to welcome some of the cast from NCIS: Hawai’i and NCIS: Los Angeles for crossovers, such as Vanessa Lachey and LL Cool J.

One big question going into season 20 is whether we will see Mark Harmon return at any point as Leroy Jethro Gibbs. When the long-standing lead of the show departed executive producer Steven D. Binder said “Regarding the future of Gibbs, as long-time fans of the show may have noticed over the years…never count Leroy Jethro Gibbs out.”

This may mean that we could see Mark back, although whether he would return as soon as season 20 is uncertain.

Here's a full list of who of the main cast and crossover stars for NCIS season 20:

  • Gary Cole as Alden Parker
  • Sean Murray as Timothy McGee
  • Wilmer Valderrama as Nick Torres
  • Katrina Law as Jess Knight
  • Brian Dietzen as Dr Jimmy Palmer
  • Diona Reasonover as Kasie Hines
  • David McCallum as Dr Donald Mallard
  • Rocky Carroll as Leon Vance
  • Vanessa Lachey as Jane Tennant
  • Jason Antoon as Ernie Malik
  • Noah Mills as Jesse Boone
  • Chris O'Donnell as Grisha 'G' Callen
  • LL Cool J as Sam Hanna
