James Walker was a Scottish professional footballer who made over 180 appearances as an inside forward in the Scottish League for Third Lanark. He took part in the club's off-season tour of South America in 1923. He also played for Dundee United and Queen's Park.
An appearance in the 1920 Home Scots v Anglo-Scots trial match was the closest he came to any international recognition.
Walker's brothers Willie and Frank were also Queen's Park footballers. He served in the Glasgow Highlanders during the First World War and was a school teacher by profession.
