Sydney George Ure Smith OBE (9 January 1887 – 11 October 1949) was an Australian arts publisher, artist and promoter who "did more than any other Australian to publicize Australian art at home and overseas". Unlike most of his contemporaries, he seldom submitted his own art work for publication. He published some of his own work in limited edition books such as Old Sydney (1911) and Old Colonial By-Ways (1928), prompted by his passion for preserving historic buildings.
