Malacothrix is a genus of plants in the dandelion tribe within the sunflower family.[2][3] They are known generally as desert dandelions or desertdandelions. Most are native to western North America although a few have been introduced to South America. Several are found only on offshore islands in the Pacific.[4]

Phylogenetic analysis demonstrates that Malacothrix is not monophyletic. Some of its species are related to Atrichoseris, whereas a second group is more closely related to Anisocoma and Calycoseris.[5]
