Jack Scalia (born Giacomo Tomaso Tedesco; June 10, 1950) is an American actor and producer. He has had many roles in television series, television movies, and feature films. He is perhaps best known for his role as Chris Stamp on All My Children from 2001 to 2003.

He is of Italian and Irish descent; his father was former Brooklyn Dodger Rocky Tedesco. His parents divorced and when his mother remarried his name was changed to Scalia. He was drafted third by the Montreal Expos in 1971 as a pitcher but he was injured and never played in the Major Leagues.

He began his career as a clothes model, most notably in a series of ads for Eminence briefs and Jordache jeans, both of which capitalized on his "beefcake" appeal. In 1982, to promote his TV series The Devlin Connection, he took off his shirt and posed, cigarette in hand, for a pin-up wall poster.

He was a regular cast member during the final season of Remington Steele in 1987, after which he joined the cast of Dallas in the role of Nicholas Pearce, love interest to Sue Ellen Ewing. His character was killed off at the end of the 1987–88 season when he fell to his death after being pushed from a balcony during a fight with J. R. Ewing. He returned to the series finale in a dream sequence in which he was married to Sue Ellen.

From 1989 to 1990, he starred in another tv series, the CBS crime drama Wolf. In 1992, he was cast as Detective Nico "Nick" Bonetti in the short-lived television series Tequila and Bonetti - he replaced another actor in the role during production of the show's first episode. Eight years later, in 2000, Scalia reprised the role of Bonetti in a revival of the series, which was filmed and aired in Italy.

In 1993, he portrayed Joey Buttafuoco in Casualties of Love: The Long Island Lolita Story, with Alyssa Milano as Amy Fisher. The footage was used in 2012 for Triple Fisher: The Lethal Lolitas of Long Island.

From 1994 to 1995, he starred in Pointman, a television series on the Prime Time Entertainment Network. He was an investment banker framed and convicted of fraud. When eventually cleared, Constantine "Connie" Harper becomes the owner of a Florida beach resort, Spanish Pete's, and aids people in need with the use of former prison mates and "the list".

He is also known for his role as Chris Stamp on All My Children from 2001 to 2003. He was nominated for a Daytime Emmy Award for "Outstanding Lead Actor" in 2002. In 2005, he portrayed Charles Keefe in the film Red Eye, with Rachel McAdams and Cillian Murphy. In 2006, he starred as President Halstrom in The Genius Club for writer/director Tim Chey.
