The 1901 Federal Flag Design Competition was an Australian government initiative announced by Prime Minister Edmund Barton to find a flag for the newly federated Commonwealth of Australia. In terms of its essential elements the winning entries are the official flag of Australia.

Sir Edmund "Toby" Barton was an Australian statesman, barrister and jurist who served as the first prime minister of Australia from 1901 to 1903. He held office as the leader of the Protectionist Party, before resigning in 1903 to become a founding member of the High Court of Australia, on which he served until his death. He was highly regarded as one of the leaders and founding fathers of the Federation movement and for his work in drafting and later interpreting the Constitution of Australia and early federal laws.
