Eula Whitehouse (1892–1974) was an American botanist, botanical illustrator, and plant collector known for gathering specimens from Africa, Hawaii, Australia, New Zealand, Cyprus, India, Singapore, Fiji, and Mexico.
She completed her PhD in 1939 with a doctoral dissertation titled, A Study of the Annual Phlox Species.

She worked at Southern Methodist University as a botany professor, head of the herbarium, and curator of the plant cryptogams.
