Mahlon Preston Hamilton, Jr. (June 15, 1880 – June 20, 1960), was an American stage and screen actor. He was the son of a bartender born in Baltimore, Maryland, the eldest of four children, with the rest of the siblings being girls. Census records indicate his mother died sometime around 1899.
Hamilton served with the Maryland National Guard and attended the Maryland Agricultural College (today the University of Maryland, College Park) before turning to acting.
From 1908 through 1914, Hamilton appeared in such plays as The Great Question, Israel, When Claudia Smiles, The Chaperon, and Overnight. He began his film career during the silent era, appearing in more than 90 films between 1914 and 1950.
