Herbert R. Gilbert (18 September 1888 – 5 January 1972) was an Australian rugby league and rugby union player – a dual-code international. He represented the Wallabies in three Tests in 1910 and the Kangaroos in seven Tests from 1911 to 1920, his last two as captain. The captain-coach of the St. George Dragons club in Sydney in their inaugural season, he is considered one of Australia's finest footballers of the 20th century. His sons, Herb Gilbert, Jr and Jack Gilbert were also notable rugby league footballers.
