James Johnston (11 August 1903 – 17 October 1991) was a Northern Irish lyric tenor, principally in opera.
Born in Belfast, Johnston had no formal training and began his working life as a butcher in his father's shop.
After positive notices of a performance in Rigoletto in Dublin in 1940, he was offered a contract with Sadler's Wells Opera, where he stayed for almost ten years, becoming principal tenor.
He made his Covent Garden debut in La Traviata opposite Elisabeth Schwarzkopf in 1949.
During his career he also appeared with Maria Callas, Joan Sutherland and Victoria de los Ángeles amongst others.
