Bebe Neuwirth (Seasons 4, 8 & 9)

Bobby Cannavale (Season 1)
District Attorney Charles Rossellini had his eye on the mayor’s office, and he needed the help of his subordinate, Erin, as well as her father Frank, to make it to Election Day without any “stinkbombs.” During his three-episode arc, he and Erin also shared a brief romantic moment.
Tovah Feldshuh (Season 5)
Sylvia Hayden was introduced as Pop’s new romantic partner, but upon further investigation by Erin, it was revealed that Sylvia was a con artist, and there was a warrant out for her arrest for grand larceny. On their next date, Henry had her arrested for her crimes.
Method Man (Seasons 5 & 7)
The Grammy-winning rapper played murderer Mario Hunt, who nearly evaded the Reagans, but finally confessed while hanging off of the ledge of a building—Danny pulled him up and put him behind bars. Then, in Season 7, Frank asked Hunt to help end a gang war.
Michael Imperioli (Seasons 7 & 11)
When Imperioli’s (The Sopranos) Robert Lewis first arrived in Erin’s office, she hadn’t seen the prosecutor since law school graduation. Working as a prosecutor for the attorney general, Lewis was sent to determine if Danny’s shooting of serial killer Thomas Wilder (Louis Cancelmi) was justified, and he bombards Nicky and Danny with questions.
Jimmy Buffett (Season 12)
In his final acting appearance before his 2023 death, the singer took on this dual role. As a con man named Dickie, he took advantage of Danny by stealing the identity of…Jimmy Buffett. Later, Buffett appeared as himself to kindly confront the identity thief.
Treat Williams (Seasons 6, 8, 9, 10, 12 & 13)

Lori Loughlin (Season 7)

Lou Diamond Phillips (Seasons 9 & 10)
The Longmire star played cartel member Luis Delgado, who Danny thought was connected to the helicopter crash that killed his wife. Later, Danny and Delgado worked together to arrest the murderer of Delgado’s wife, before Delgado was put in prison for past crimes.
Tony Danza (Season 12)
Danza (Taxi) appeared as Lieutenant Moretti, who got in trouble for housing his son while knowing about his gang-related ties. Frank made it clear that keeping other kids on the straight and narrow “does not cancel out his own son being on the wide and crooked.”
Stacy Keach (Seasons 7, 8, 9, 10, 12 &13)
As Archbishop Kearns, the Shakespearean star became involved in a number of Frank’s high-profile cases. Although Kearns was unwilling to help Frank get the evidence he needed when they first met, the two later became close friends with much in common.
Whoopi Goldberg (Seasons 6, 8 & 11)
The cohost of The View appeared in three episodes as city councilwoman Regina Thomas, who attempted to overturn a policy Frank felt was vital to the NYPD’s work. In Season 8, they became allies against the mayor, but in Season 11 they fought over police brutality.
Lyle Lovett (Seasons 10, 12 & 13)
The “Cowboy Man” crooner took on the uniform of a serious- minded Texas Ranger named Waylon Gates for three episodes. While working with Danny, the pair tracked a Southern serial killer and fought against drug cartels as well.
Danny Trejo (Season 9)
One of Hollywood’s favorite tough guys made an appearance as Jose Rojas—a criminal who not only killed Delgado’s wife, but Danny’s as well. Rather than fulfilling Delgado’s wishes and killing him in the name of revenge, Danny chose to arrest him.
