Harold A. Lockwood (April 12, 1887 – October 19, 1918) was an American silent film actor and one of the most popular matinee idols of the early film period during the 1910s. Often paired with actress May Allison, the two became possibly the first celebrated on-screen romantic duo. The two first shared the screen opposite one another in the Allan Dwan directed romantic film David Harum and would appear in over twenty-three films together during the World War I era. However, the two were never romantically involved off-screen. Lockwood was also among the all-star ensemble cast of the 1916 D.W. Griffith directed classic Intolerance which included Lillian Gish, Robert Harron, Mae Marsh, Douglas Fairbanks, Sam De Grasse, Wallace Reid, Mildred Harris and Carol Dempster. Lockwood died on October 19, 1918 after contracting the Spanish influenza virus. Lockwood was 31 years old. He is buried in the Woodlawn Cemetery in the Bronx. His son, Harold Lockwood, Jr. (born 1908 - ??) later appeared in silent and sound films. Amongst his earliest credits is the 1928 WW1 film Lilac Time starring Colleen Moore and Gary Cooper.
