Adelaide, city (1991 pop. 957,480), capital and chief port of South Australia, S Australia, at the mouth of the Torrens River on Gulf St. Vincent. It has automotive, textile, and other industries. Grains, wool, dairy products, wine, and fruit are exported. In the face of declining manufacturing, service industries have become more important.

Named for the consort of William IV, it was founded in 1836 and is the oldest city in the state. It was the first city in Australia to be incorporated (1840) and developed according to the original city plan of Colonel William Light. The Univ. of Adelaide (1874) and the multicampus South Australian College of Advanced Education (1982) are among the institutions of higher education located in the city and its suburbs. The Adelaide Festival of the Arts has been held biennially since 1960.
