阿瑟·米恩（Arthur Meighen）（1874年6月16日－1960年8月5日），是加拿大第10、12任总理，首位在加拿大联邦成立后出生的总理。

Arthur Meighen, PC, QC (/ˈmiːən/; 16 June 1874 – 5 August 1960) was a Canadian lawyer and politician. He served two terms as the ninth Prime Minister of Canada: from 10 July 1920 to 29 December 1921; and from 29 June 1926 to 25 September 1926. He was the first Prime Minister born after Confederation, and the only one to represent a riding in Manitoba. Both of his terms of office were brief. Meighen later served for a decade in the Senate of Canada, and failed in a political comeback attempt in 1941–42, after which he returned to the practice of law. Larry A. Glassford, a professor of education at the University of Windsor, concluded, "On any list of Canadian prime ministers ranked according to their achievements while in office, Arthur Meighen would not place very high."
