Carl Linger (1810–1862) was a German Australian composer who wrote the "Song of Australia". For his song he received a price of ten guineas.
German-born intellectual Carl Linger, who had studied at the Institute of Music in Berlin, came to South Australia in 1849 on the Princess Luise. He settled in Gawler, grew potatoes, went broke and settled in Adelaide. Here he was far more successful. He was the founder and conductor of the German Liedertafel in 1858 and composer of church music, including the "Ninety-third Psalm", "Gloria", "O Lord who is as Three" and "Vater unser". For several years he played the harmonium at St Frances Xavier Cathedral. When he died he was buried at the West Terrace Cemetery. Later, as part of the State's Centenary, a monument was built on his grave.
