George Collingridge (1847–1931) was an Australian writer and illustrator best known today for his early assertions of Portuguese discovery of Australia in the 16th century.

His publication of The Discovery of Australia in 1895 earned him accolade as a "genius" and as "an authority on geographical matters" from members of the Royal Geographical Society as well as foreign honours: in 1908 he was created a Knight Commander of the Order of Santiago by the King of Portugal. In 1917 he was made a Knight Commander of the Order of Isabella la Catolica by the King of Spain.
