The 1906 Australian federal election was held in Australia on 12 December 1906. All 75 seats in the House of Representatives, and 18 of the 36 seats in the Senate were up for election. The incumbent Protectionist Party minority government led by Prime Minister Alfred Deakin retained government, despite winning the fewest House of Representatives votes and seats of the three parties. Parliamentary support was provided by the Labour Party led by Chris Watson, while the Anti-Socialist Party, led by George Reid, remained in opposition.

The House of Representatives is the lower house of the bicameral Parliament of Australia, the upper house being the Senate. Its composition and powers are set down in Chapter I of the Constitution of Australia.
