Eric Cuthbert Christmas (March 19, 1916 — July 22, 2000) was a British-Canadian stage and screen actor, with over 40 films and several more television roles to his credit. He was well-known for his role as Mr. Carter, the principal of Angel Beach High School, in the 1982 hit comedy Porky's, the 1983 sequel Porky's II: The Next Day, and the 1985 sequel Porky's Revenge.

Christmas was born in London, UK and later immigrated to Canada. His role as a priest in the 1971 film Harold and Maude includes a memorable monologue to an off-camera Harold, in which he discusses, with increasing nausea and disgust, how the thought of Harold's sexual affair with a much older woman "makes [him] want...to vomit." His other film roles include The Philadelphia Experiment (1984), Bugsy (1991), Almost Dead (1994), Naked Gun 33⅓: The Final Insult (1994), Air Bud (1997), and his final feature film Mousehunt (1997).

Christmas also made guest appearances in many television shows, including Adventures in Rainbow Country, ER, Night Court, Seinfeld, Cheers, Home Improvement, The X-Files, Booker, Matlock, Walker Texas Ranger, and Ally McBeal. He also acted in and directed productions of San Diego, California's Old Globe Theatre's Shakespeare Festivals for many years.

In the 1970s, Christmas was a drama professor at the University of California, San Diego.

Christmas trained at the Royal Academy of Dramatic Art, gained experience in English repitory theatre in 1936, and had a principal role in the London production of Noel Coward's "Bitter Sweet" in the 1930s. During the Second World War, he was a member of Royal Air Force production units, and performed in the RAF's Gang Show. After moving to Canada in 1948, he started a long association with television comedians Wayne & Shuster, playing the character Madam Hooperdink. His own show "Christmas is Coming" toured Canada in the 1950s. He began a long association with Canada's Stratford Festival in 1957, performing in 12 seasons and 21 Shakespearean productions until 1970. It was Christmas and a group of veteran actors like William Hutt, Tony Van Bridge, Jean Gascon, Douglas Rain, Amelia Hall, and Mervyn Blake (among others) who helped define Stratford in its early years. His final appearance at Stratford was 1987, when he played Dogberry in Much Ado About Nothing. Christmas also had associations over the years with the Canadian Players, San Diego's Globe Theatre, and the drama department at the University of California at San Diego. He and his wife Marcy had three children (Robin, Holly, Kailee), six grandchildren.
