William Camphin (13 November 1867 – 11 September 1942) was an Australian cricketer.

Perhaps his most notable cricketing achievement was a score of 71 made in a non first-class tour game against Lord Sheffield's English team at the Sydney Cricket Ground.

Outside of cricket Camphin was a violinist with the Sydney Liedertafel orchestra and played at the opening of St. Mary's Cathedral in 1883.

In his career he was a lawyer having joined the Public Service in 1885 and in 1896 he was appointed deposition clerk at the Central Police Court.

In 1923 he was appointed to the Sydney Metropolitan Bench and he served on the body until retiring in 1932 as he was considered too old to continue in the position.
