Michael Fitzgerald Dunn (1842 - March 25, 1913) was a New Orleans Irish-American lithographer and stationer active in the late 19th century. He partnered for a time in the 1879s with Thomas Fitzwilliam from offices at 76 Camp Street, before establishing his own firm, M. F. Dunn and Brothers. They were based at 70 Camp and at 67 Washington Ave, New Orleans. Dunn operated one of the first steam presses in New Orleans.
