Henry Johnson (18 May 1819 – c. 11 October 1891), better known by his alias Harry Power, was an Irish-born convict who became a bushranger in the Australian colonies.

"[5] He was convicted at Salford, Lancashire, on 31 August 1840, and was sentenced to transportation for seven years to Australia for stealing a bridle and saddle, under the name of Henry Johnson, and adhered to that name until he became a ticket-of-leave man.

[citation needed] Power was engaged driving cattle all over Victoria and New South Wales, and later joined Captain Denman's party in exploring and cutting a track across the ranges.

During all this time he appears to have been getting an honest living, even keeping a horse yard at Geelong, which is ostensibly a respectable calling.

But I was frightened, and rode across the colony, thinking to go and stay in New South Wales till the row was over.

[citation needed] Escaping from Pentridge Prison in 1869, the 50-year-old Power turned to highway robbery and became known as a bushranger.

[13] He was arrested while sleeping in a hut on the Glenmore Run which was squatted by the Quinn family, Ned Kelly's grandparents and uncles.

[citation needed] In late 1891 Harry Power fell into the Murray River and drowned at Swan Hill,[8] possibly while fishing.

On November 8 (a few days after the discovery), the drowned man was identified as Harry Power.

[17] Power's relationship with Kelly is depicted in the 1980 miniseries The Last Outlaw, where he was played by Gerard Kennedy.

[18] The relationship is also depicted in Peter Carey's Booker Prize–winning novel True History of the Kelly Gang.

In the film adaptation of the novel, Power is portrayed by Russell Crowe, opposite Orlando Schwerdt as a young Ned Kelly.
