Blue Bloods, like any good police procedural, is filled with characters played by guest stars who appear in only a handful of episodes, but still make memorable appearances.
This season, Blue Bloods brought in Lou Diamond Phillips as a new villain for Detective Danny Reagan (Donnie Wahlberg), and has already become a fan-favorite character. Comedian Aasif Mandvi also joined in a surprisingly serious part.
Many of the show's guest stars appear in just one episode, but a few have popped up frequently over the years. Kevin Dillon has appeared as Danny's son-in-law a few times, while Lorraine Bracco appeared as a liberal New York politician who clashed with Commissioner Frank Reagan (Tom Selleck).
Scroll on for a look at some of the best guest stars Blue Bloods has had. New episodes air on Fridays at 10 p.m. ET. on CBS.

Lou Diamond Phillips
Lou Diamond Phillips is playing Luis Delgado, the man who torched Danny's house at the end of season seven. Delgado, a hitman for the Mexican cartels Danny is investigating, was thought to be dead at the end of the season nine premiere. However, it turns out he was alive and is now on the run. He also revealed that Danny's wife, Linda (Amy Carlson) did not die in a helicopter accident as previously thought. Linda's death was ordered by a cartel in retaliation for Danny's investigation.prevnext
