James Garfield "Jimmie" Schaeffer was an American college football coach. He served as the University of California head football coach from 1909 to 1915 and amassed a 73–16–8 record. From 1909 to 1914, California played football according to the rugby code, rather than the American code. He also coached the Cal baseball team from 1911 to 1915 and amassed a 39–21–2 record. Schaeffer resigned from both posts in November 1915.
