Three new species of Lepanthes from Ecuador are described and illustrated. These additions to the Ecuadorean flora were recorded in evergreen montane forest and páramo as part of three different research projects conducted during the last five years (2016-2021). Lepanthesoro-lojaensis was discovered in the southwest of El Oro province and is similar to L.jimburae, differing mainly in the much smaller plants, inflorescences and floral parts. Lepanthesmicroprosartima from the western slopes of Pichincha volcano in northern Ecuador resembles L.obandoi but differs in the coloration of the leaves, the inflorescence that are shorter than the leaves and the smaller floral appendix. Lepanthescaranqui, found in eastern Pichincha and Imbabura, is most similar to L.pachychila but differs from it in its much larger plants and different shape of the petals and the floral appendix. Preliminary assessments of the conservation status of the three taxonomic novelties are provided, using the IUCN Red List Categories and Criteria.
