Walsh was born Charles Hunter Walsh in Los Angeles, California. His maternal grandfather, Frank P. Haven, was a managing Editor of the Los Angeles Times. His parents worked for the Foreign Service—they met in Ethiopia. As a result, Walsh lived in East Africa, India, Pakistan and Indonesia as a boy. His family returned to the United States when he was ten years old and settled in Virginia, where Walsh began acting in high school. He graduated from the University of Virginia in 1986 with a degree in English. After graduating from college, Walsh moved to New York City to act professionally.
