Sir William Elliot Johnson KCMG (10 April 1862 – 8 December 1932) was an Australian politician.

He ran away from home at 13, worked in the telegraph office at London, and afterwards assisted his father scene-painting at Covent Garden theatre.

[1][2] Johnson was an early member of the Labor Electoral League of New South Wales and served as president of its Newtown branch.

Johnson later left the party on the grounds that it had "turned wrongly towards socialism and state interference".

Johnson was a man of great industry who made it his business to be thoroughly acquainted with the subjects under debate.
