The National War Memorial (South Australia) is a monument on the north edge of the city centre of Adelaide, South Australia that commemorates South Australians who served in the First World War and those who gave their lives. It was opened in 1931. The memorial is on the corner of North Terrace and Kintore Avenue, next to the grounds of Government House. Observances are held at the site throughout the year, with major services on Anzac Day (25 April) and Remembrance Day (11 November).

North Terrace is one of the four terraces that bound the central business and residential district of Adelaide, the capital city of South Australia. It runs east–west, along the northern edge of "the square mile". The western end continues on to Port Road, and the eastern end continues across the Adelaide Parklands as Botanic Road.
