Maxwell Stanley Ruddock (2 January 1914 – 31 May 1976) was a New South Wales politician, Assistant Treasurer and Minister of the Crown in the cabinets of Tom Lewis and Sir Eric Willis.

Representing the Liberal Party he was a member of the New South Wales Legislative Assembly for 14 years from 3 March 1962 until his resignation on 25 May 1976.

He held these ministries until Lewis was replaced as Premier by Sir Eric Willis, who then reappointed him as Assistant Treasurer and Minister for Revenue on 23 January 1976.

A state funeral at St James' Chapel, Castle Hill, was held for him, which was attended by the Governor, Sir Roden Cutler.
