William Hector Cerutti (7 May 1909 – 3 July 1965) was an Australian rugby union international during the 1920s and 1930s.

Initially a soccer player, he got started in grade rugby in 1925 at the YMCA club, making it into the first XV the following year.

On the 1928 New South Wales tour of New Zealand, he featured in four matches which were retrospectively given Test status, as Australia's only representative team at that point in history.

He was a permanent fixture in the Australian team until 1933, with sporadic appearances afterwards, before his international career was ended by his surprise omission from the 1939–40 tour of Britain and Ireland.

He spent his career with YMCA, Glebe-Balmain, Parramatta, Eastern Suburbs and St. George, before retiring in 1946.
