William Edward "Billy, Pud" Hamilton (February 10, 1874 – October 23, 1965) was a Canadian professional ice hockey defenceman who was active in the early 1900s.

Hamilton played for the Pittsburgh Athletic Club in the Western Pennsylvania Hockey League, as well as for the Michigan Soo Indians in the International Professional Hockey League.

He also appeared in two games with the Pittsburgh Bankers.

Pud Hamilton played with a rough edge to his game and a Pittsburgh Press report from January 1904 says he was released by manager Charles Miller of the Pittsburgh Athletic Club on account of his temper.
