We present taxonomic notes, including updated species descriptions and images, for the nine species of Agrostis and one species of Podagrostis found in páramos of Departamento Boyacá, Colombia (A. boyacensis, A. breviculmis, A. capillaris, A. foliata, A. cf. imberbis, A. mertensii, A. perennans s.l., A. stolonifera, A. tolucensis, Podagrostis trichodes). Agrostis cf. imberbis, previously known from austral South America, is newly recorded for Colombia, A. capillaris is a new regional record for Boyacá, and the name Agrostis stuebelii is lectotypified. We include keys in English and Spanish to distinguish the 15 species of Agrostis and two species of Podagrostis that are cited as occurring in Colombia.
