Peter Dodds McCormick (1834? – 30 October 1916), a Scottish-born schoolteacher, was the composer of the Australian national anthem "Advance Australia Fair".
Born the son of a seaman at Port Glasgow, Scotland, he arrived in Sydney (at that time the principal city of the British colony of New South Wales) in 1855. He worked as a joiner for "some years". Details of his earlier years, prior to his arrival in Australia, are shadowy. He spent most of his life employed by the NSW Education Department. In 1863 he was appointed teacher-in charge of at St Mary's National School and went on to teach at the Presbyterian denominational school in the Sydney suburb of Woolloomooloo in 1867. He then moved to Dowling Plunkett Street Public School in 1878 where he remained until 1885.
McCormick was heavily involved in the Scottish Presbyterian Church and was active in a number of community and benevolent organisations. He began his involvement with Sydney's St Stephen's Church as a stonemason, working on the now demolished Phillip Street Church (where Martin Place now stands). The Rev Hugh Darling was so impressed with his singing on the job he asked him to join the choir. McCormick's musical ability led him to becoming the precentor of the Presbyterian Church of NSW, which gave him the opportunity to conduct very large massed choirs. He was also convenor of the Presbyterian Church Assembly's Committee on Psalmody.
Also a talented composer, he published around 30 patriotic and Scottish songs, some of which became very popular. Included in his collected works was Advance Australia Fair, which was first performed in public by Andrew Fairfax at the St Andrew's Day concert of the Highland Society on 30 November 1878.
