Os Deane (1890-1955) was an Australian rugby league footballer who played in the 1900s and 1910s. He played in the NSWRFL premiership for North Sydney as a utility.
Deane began his first grade career in 1909 against Western Suburbs in a 5–5 draw. In 1913, Deane was selected to represent New South Wales when they toured New Zealand. Deane made 5 appearances on tour and scored two tries.
Deane was one of the club's longest serving players in the early years but his time at the club was not a successful one with the club failing to make the finals and finished last on the table twice.
Deane was the brother of Lal Deane who later became a referee and Sid Deane who represented Australia, New South Wales and was named in the North Sydney Bears team of the century.[2]
