Robert John is an American singer-songwriter perhaps best known for his 1979 hit single, "Sad Eyes", which reached number 1 on the US Billboard Hot 100.

Sir Henry Paulet St John, 2nd Baronet (1737–1784), was a British politician who sat in the House of Commons from 1772 to 1780.

Al St. John was an early American motion-picture comedian and a nephew of silent film star Roscoe “Fatty” Arbuckle, with whom he often performed on screen. St. John was employed by Mack Sennett and also worked with many other leading players such as Charlie Chaplin, Buster Keaton and Mabel Normand. His film career successfully transitioned from the silent era into sound, and by the late 1930s and 1940s he was working predominantly in Westerns, often portraying the scruffy comedy-relief character "Fuzzy Q. Jones". Among his notable performances in that role are in the "Billy the Kid" series of films released by the Producers Releasing Corporation from 1940 to 1946 and in that company's "Lone Rider" series from 1941 to 1943.
