Latest studies have contributed to the floristic knowledge of Guerrero state, however, there are still regions that have not been studied, for example, the north of Guerrero, where the municipality of Buenavista de Cuellar is located. This municipality belongs to the priority terrestrial region 120 "Sierras de Taxco-Huautla". Therefore, this paper presents the floristic inventory, an floristic similarity analysis and the vegetation types from the municipality of Buenavista del Cuellar. The floristic list includes 611 species, 331 genera, and 94 families distributed in five vegetation types: Juniper forest, pine-oak forest, oak forest, tropical deciduous forest and grassland. The tropical deciduous forest is the most diverse, with 47.62% of the vegetal species in Buenavista de Cuellar. Magnoliophyta is the group that provides the greatest specific richness with 96.07%. The best represented families are Asteraceae (81 species), Fabaceae (60), Apocynaceae (28) and Convolvulaceae (22). Besides, there were found 29 endemic species for Mexico, 11 for Cuenca del Balsas and 4 for Guerrero. The floristic similarity analysis of Buenavista de Cuellar with the Sierra de Taxco, Sierra de Huautla and "General Juan N. Álvarez" National Park, showed the greatest similarity of the study site with Sierra de Huatla.
