Marie Leonore Farr (1927–2014), known as Lennie Farr, was an American mycologist. She was the first woman to be elected president of the Mycological Society of America.
Marie Lenore Ehrmann was born in Vienna, Austria on September 6, 1927. She migrated to the United States with her family and completed her secondary education at Central High School in Detroit, Michigan in 1945.

Farr worked at a number of universities both in the United States and elsewhere, including Washington State College, Smith College, the Institute of Jamaica and Federal University of Pernambuco in Brazil. She then joined the Mycology Laboratory at the United States Department of Agriculture in Beltsville, Maryland. She collaborated locally and internationally in the identification of slime molds and ascomycetes.
