John Allan (27 March 1866 – 22 February 1936) was an Australian politician who served as the 29th Premier of Victoria. He was born near Lancefield, where his father was a farmer of Scottish origin, and educated at state schools. He took up wheat and dairy farming at Wyuna and was director of a butter factory at Kyabram. In 1892 he married Annie Stewart, with whom he had six children. A 1928 oil portrait of Allan by artist Aileen Dent hangs in the Victorian Parliament House.
