The Electoral district of Brown Hill-Ivanhoe was a Legislative Assembly electorate in the state of Western Australia. It covered part of the Goldfields city of Boulder, near Kalgoorlie, and neighbouring mining areas. It was created at the 1911 redistribution out of the former seats of Brown Hill and Ivanhoe, and was first contested at the 1911 election. It was abolished in the 1948 redistribution, with its area split between the neighbouring electorates of Boulder and Hannans, taking effect from the 1950 election. The seat was a very safe one for the Labor Party.

Elections were held in the state of Western Australia on 3 October 1911 to elect 50 members to the Western Australian Legislative Assembly. The Labor Party, led by Opposition Leader John Scaddan, defeated the conservative Ministerialist government led by Premier Frank Wilson. In doing so, Scaddan achieved Labor's first absolute majority on the floor of the Assembly and, with 68% of the seats, set a record for Labor's biggest majority in Western Australia. The record would stand for nearly 106 years until Labor won 69% of seats at the 2017 election. The result came as something of a surprise to many commentators and particularly to the Ministerialists, as they went to an election for the first time as a single grouping backed by John Forrest's Western Australian Liberal League, under a new system of compulsory preferential voting and new electoral boundaries both of which had been passed by Parliament earlier in the year despite ardent Labor opposition.
