Marguerite L. Gillespie (1892 - October 16, 1976) was a commercial artist active in Portland, Oregon, from the early 1930s through at least the mid-1940s. She created several pictorial maps for The Sunday Oregonian, many of which were then sold as separate issues due to their popularity. In the 1930s Gillespie worked for the Beaver Engraving Company, which was founded in 1909 in Portland and still operates today.
