List of Astragalus species

This list is incomplete; you can help by expanding it.

This is a list of Astragalus species, including infraspecific taxa. They are listed according to subgenera (for Old World species) or informal groups called phalanxes (for North American species). Subgenera and phalanxes are further subdivided into sections.^[1]^[2]^[3]^[4]^[5]^[6] Phylogenetic analyses have determined that many of these subgenera, phalanxes, and sections are not monophyletic.^[7]^[8]^[9]^[10]^[11]^[12]^[13]^[14]^[15]^[16]^[17]^[18]^[19]^[20]^[21]^[22]
