"Youngia" is an Asiatic genus of Asteraceae. There are several weed species in the genus including the endangered "Youngia nilgiriensis" Babcock from Sispara and "Youngia japonica", which is also known as Japanese Hawkweed.

"Youngia" was first described in 1831 by H. Cassini, and the genus was later united with "Crepis". Taxomonic and cytogenetic studies by E. B. Babcock and G. Ledyard Stebbins led to the reclassification of the genus in the 1930s.
