John Pringle AM (born 17 October 1938) is a retired Australian operatic baritone. He sang leading and supporting roles with Opera Australia and its predecessors for 41 years (1967–2008), and with some overseas companies. He was strongly associated with roles by Mozart, such as Figaro and Count Almaviva in The Marriage of Figaro; the title role and Leporello in Don Giovanni; Guglielmo and Don Alfonso in Così fan tutte; and Papageno in The Magic Flute.
John Pringle started his adult life as a pharmacist for five years, with a degree from the University of Melbourne. At the age of 28 music took over and in 1967 he won the Melbourne Sun Aria award. He had been singing in some amateur shows around Melbourne, and used his friendship with John Cargher to gain some valuable contacts in the opera world.
His debut was in the Australian Opera's 1967 production of Die Fledermaus, at the Princess Theatre, Melbourne, alongside singers such as Robert Gard and June Bronhill. Gard also appeared in Pringle's final performance in 2008.
In 1973 he was part of the company's historic first season at the Sydney Opera House, singing the role of Count Almaviva in The Marriage of Figaro. He did not appear in the very first opera production at the Opera House, Prokofiev's War and Peace, but he sang Prince Andrei in later productions of that opera.
