Matthew John Armstrong (born August 28, 1973 in Chicago, Illinois, U.S.) is an American actor. He is known for roles in Turks (1999), The Profile (2010) and Heroes (2006).
He was most recently seen in the television series Heroes as Ted Sprague and a single episode of House. He also had a long-running role on American Dreams, and acted as a phoenix in one episode of Supernatural. He attended Naperville Central High School in Naperville, Illinois, where he played football and was the two-time Defensive Player of the Year in the DuPage Valley Conference. On May 4, 2012, he was recognised as a Naperville Central Alumni.
Armstrong reportedly has been mistaken as one of the actors who portray cavemen in a popular series of commercials for the automobile insurance provider GEICO, due to his hairstyle and facial hair resembling the makeup used for the caveman characters. Armstrong noted this misconception in an interview with Entertainment Weekly stating, “For the record, I am not the GEICO caveman.”
He is married to Ashley Crow, the actress who portrayed Sandra Bennet on Heroes. He has one son, Pete Crow-Armstrong, who was selected 19th overall in the 2020 Major League Baseball Draft by the New York Mets.
