'''''Henssenia''''' is a genus of lichen-forming fungi in the family Koerberiaceae. It has four species.<ref name="Wijayawardene et al. 2022"/> The genus was circumscribed in 2017 by Damien Ertz, Roar Skovlund Poulsen, and Ulrik Søchting, with ''Henssenia glaucella'' assigned as the type species. The main distinguishing characteristic of the genus is simple ascospores (i.e., lacking septa) that sometimes have a plasma bridge. The genus name honours German lichenologist Aino Henssen.<ref name="Ertz et al. 2017"/>
