Jerry Adler (born February 4 1929) is an American theatre director, production supervisor and a television and film actor.

Adler was born in Brooklyn, New York to Pauline and Philip Adler, a general manager of the Group Theatre. Adler began his theatre career as a stage manager in 1951, working on such productions as Of Thee I Sing and My Fair Lady before becoming a production supervisor for The Apple Tree, Black Comedy/White Lies, Dear World, Coco, 6 Rms Riv Vu, Annie, and I Remember Mama, among others. He made his directing debut with the 1974 Sammy Cahn revue Words and Music and also directed the 1976 revival of My Fair Lady, which garnered him a Drama Desk Award nomination, and the ill-fated 1981 musical The Little Prince and the Aviator.

As an actor, Adler is perhaps best known for his roles as Herman "Hesh" Rabkin in The Sopranos, Mr. Wicker in Mad About You, and Lt. Al Teischler in Hudson Street. His screen credits include In Her Shoes and Manhattan Murder Mystery. In addition, Adler also appeared in an episode of The West Wing as Toby Ziegler's father, Jules Ziegler. The elder Ziegler worked as a member of Murder, Inc. in the 50's. Adler is now appearing as the new chief in the fourth season of FX's fire fighter drama Rescue Me.
