Rev. John Norman Maclean (Scottish Gaelic: an t-Urr. Iain Tormod MacGilleEathain) (1862–1941) was a Scottish-Canadian Presbyterian minister who emigrated to the United States and served in congregations in California, Iowa, and Montana.
Rev. Maclean is best known as the father of American author Norman Maclean. Norman Maclean wrote vividly about his family in both fictionalized and non-fictional accounts, including the bestseller, A River Runs Through It, which remains an iconic work of 20th century American literature.
