James MacNaughton (March 4, 1864 - May 27, 1949), also variously known as "the King of Houghton County", the "Czar of the Copper Country" or simply "Big Jim" was an American business executive.

He was general manager and the third president of the Calumet and Hecla Mining Company, including during the Copper Country Strike of 1913–1914.

In 1876 and aged 12, MacNaughton followed his father's footsteps by becoming Hecla's water boy in Hubbell, Michigan.

When interviewed, MacNaughton blamed the Western Federation of Miners for the strike, We have Croatians, Austrians, Hungarians, Italians from northern Italy, Poles, and other nationalities working for us, and they are industrious, loyal men; but they do not know our language or our customs, our laws, nor our ideals.
