The season finale of Boston Blue premieres on Friday, May 22 and fans already can't wait for more Reagan drama in season two.
The Blue Bloods spinoff follows Danny Reagan, played by Donnie Wahlberg, after he was transferred to the Boston Police Department (BPD). Boston Blue premiered in October 2025 and was already renewed for a second season. Keep reading to get the latest updates on season two of the "compelling" CBS show.
When is Boston Blue coming back with a new season?
Boston Blue is returning for season two in late September 2026 or early October 2026. The announcement was made at the end of 2025. "These early renewals reflect the power of character-driven storytelling, compelling narratives and the exceptional talent on both sides of the camera that make these series truly stand out," said Amy Reisenbach, president of CBS Entertainment.

Tom Selleck starred Police Commissioner Frank Reagan in Blue Bloods for 14 years until the series concluded in December 2024. Appearing as the patriarch of the Reagan family, Tom acted alongside Donnie, Will Estes, and Bridget Moynahan, meaning his character exists in the Boston Blue world.
But, it isn't likely that Tom will appear in the spinoff show.

Who will return to season two of Boston Blue?
The lead of the show, Donnie, is excited to return to the set of Boston Blue. And he was lucky enough to tell the rest of the cast about the renewal. "I had the pleasure of calling all my cast mates and telling them… that we were getting a season two," Donnie told People in March 2026.

While Jenny isn't starring in Boston Blue yet, Sonequa Martin-Green, who is returning as Lena Silver, told UsWeekly in April 2026: "I'm always texting with Jenny and Donnie’s always texting with [my husband] Kenric [Green]. So we have this really interesting four part friendship going on, which is growing and it's really sweet. But we talk about Jenny coming on the show all the time."
