The Selected Journals of L. M. Montgomery, Vol. I–V, are the personal journals of famed Canadian author, Lucy Maud Montgomery (1874–1942).
Montgomery left all of her journals and scrapbooks to her son, Dr. E. Stuart Macdonald, who kept them until 1981, when he donated them to the University of Guelph in Ontario, Canada. Mary Rubio and Elizabeth Waterston of the University of Guelph co-edited all five volumes of these journals, which were ultimately published between 1985 and 2004 by the Oxford University Press. The five volumes are:
• The Selected Journals of L.M. Montgomery, Volume I: 1889–1910 (published in 1985)
• The Selected Journals of L.M. Montgomery, Volume II: 1919–1921 (published in 1987)
• The Selected Journals of L.M. Montgomery, Volume III: 1921–1929 (published in 1992)
• The Selected Journals of L.M. Montgomery, Volume IV: 1929–1935 (published in 1998)
• The Selected Journals of L.M. Montgomery, Volume V: 1935–1942 (published in 2004)
