Type species
Lessingia germanorum

Lessingia is a genus of plants in the family Asteraceae which are native to western North America. Several species are endemic to California.

Lessingias are generally daisy-like in appearance with white, yellow, or purple flowers, but they vary in appearance. Some lessingias are sometimes treated as members of different genera, such as Benitoa. The San Francisco lessingia, Lessingia germanorum, is an endangered species.
