Sir John Madden, GCMG (16 May 1844 – 10 March 1918) was an Australian judge and politician who was the fourth and longest-serving Chief Justice of Victoria, in office from 1893 until his death.

The family moved to London, UK in 1852, where his father had taken a job managing an insurance company, and there Madden attended a private school.

In January 1857, the family emigrated to Melbourne, Australia, where John Madden senior was admitted as a barrister to the Victorian Bar.

Madden was admitted to the Victorian Bar on 14 September 1865, where he established a good reputation for himself, particularly in equity and criminal law matters.

After McCulloch's resignation in May 1877, Madden left the ministry, but returned in March 1880 when he was made Minister for Justice in the Service government.

He was considered one of the leaders of the Victorian Bar at this time, to the extent that by 1890, he was involved in about thirty percent of all cases coming before the Supreme Court of Victoria.

After viewing the car's performance, and the driving skill of the two managers, he promptly found in favour of the horse owner, awarding him £250 in damages.

in 1911 Sir John accepted the role of President of The Melbourne Savage Club, a position he enjoyed and held until his demise in 1918.
