Harold Eugene "Hal" Roach, Sr. (January 14, 1892 – November 2, 1992) was an American film and television producer and director from the 1910s to the 1990s.

Hal Roach was born in Elmira, New York. A presentation by the great American humorist Mark Twain impressed Roach as a young grade school student.

After an adventurous youth that took him to Alaska, Hal Roach arrived in Hollywood in 1912 and began working as an extra in silent film. Upon coming into an inheritance, he began producing short comedies in 1915 with his friend Harold Lloyd, who portrayed a character known as "Lonesome Luke." In 1915 Roach married actress Marguerite Nichols. They had two children, Hal, Jr. and Margaret (1921-1964).
