Lily Harmon (born Lillian Perelmutter; 1912–1998) was an American visual artist.

[2] While studying in Paris, she would often get up at 6:30 in the morning, take the bus around town, and sketch people doing their daily work.

She also studied textile design where she learned a lot about abstract lines, and color.

[3] Harmon illustrated books in the period 1945–1976, including by such authors as Franz Kafka, Andre Gide, Jean-Paul Sartre, Thomas Mann, and Edith Wharton.

Her first solo gallery show took place at Associated American Artists in 1994, in New York.
