'''''Draba weberi''''' is a species of flowering plant in the family Brassicaceae known by the common names '''Weber's whitlow-grass''' and '''Weber's draba'''. It is narrowly endemic to Summit and Park Counties, Colorado, where several populations were estimated to total to approximately 300 individuals as of 2012. ''D''. ''weberi'' is principally threatened by alterations to its hydrologic environment, owing to its preference for wet, rocky streamside crevices.<ref name="NatureServe" />
''Draba weberi'' is a perennial herb which grows in small, dense tufts with pubescent stems 2 to 6 centimeters long. Flowering occurs from June to July, whereupon five to 15 small yellow flowers are produced per stem. Along with several other members of the genus ''Draba'', ''D. weberi'' produces sterile pollen and reproduces asexually through agamospermy. Consequently, its seeds are formed without fertilization and carry only maternal genes.<ref>{{Cite web|url=https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5206846.pdf|title=Draba weberi Price & Rollins (Weber's draba): A Technical Conservation Assessment|last=Decker|first=Karin|date=July 31, 2006|website=USDA Forest Service, Rocky Mountain Region, Species Conservation Project|archive-url=https://web.archive.org/web/20170223062642/https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5206846.pdf|archive-date=February 23, 2017|access-date=}}</ref>
