Catherine 'Kate' Furbish (May 19, 1834 – December 6, 1931) was an American botanist who collected, classified and illustrated the native flora of Maine. She devoted over 60 years of her life, traveling thousands of miles throughout her home state and creating very accurate drawings and watercolor paintings of the plants she found. She discovered two plants which were named after her: Pedicularis furbishiae (Furbish lousewort) and Aster cordifolius L., var. furbishiae.
