Georg Tintner, CM (22 May 1917 – 2 October 1999) was an Austrian-born conductor whose career was principally in New Zealand, Australia, and Canada.
As a child he was a singer in the Vienna Boys' Choir, directed by Franz Schalk. At the Vienna State Academy he studied composition with Joseph Marx and conducting with Felix Weingartner. Soon he was assistant conductor of the Vienna Volksoper.
Due to the persecution of Jews, Tintner moved out of Vienna in 1938, arriving in Auckland, New Zealand in 1940. He conducted a church choir until after the war, when he took over the Auckland Choral Society in 1947, and the Auckland String Players in 1948. He became a New Zealand citizen in 1946. In 1954, he went to Australia and became resident conductor of the National Opera of Australia (a private company) before joining the Australian Elizabethan Theatre Trust Opera in 1957. Tintner is credited with pioneering televised opera in Australia.
He spent a year with the Cape Town Municipal Orchestra (1966–67) and three years with Sadler's Wells Opera (1967–70) before returning to Australia as Music Director of the West Australian Opera. In 1974, he rejoined the Australian Elizabethan Theatre Trust Opera, by then known as the Australian Opera. He became Music Director of the Queensland Theatre Orchestra in 1976.
