Emmanuelia is a genus of lichen-forming fungi in the subfamily Lobarioideae of the family Peltigeraceae. It has 12 species. It was circumscribed in 2020 by Antoine Simon, Robert Lücking, and Bernard Goffinet. They assigned Emmanuelia ravenelii as the type species, reasoning "this is probably the best-documented species of the lineage and its identification is straightforward". The genus name honours Belgian lichenologist Emmanuël Sérusiaux, "for his extensive contributions to advancing our understanding of the diversification of the Peltigerales".
