Nothoscordum is a genus of New World plants in the onion tribe within the Amaryllis family. It is probably paraphyletic. The genus is native to North, Central and South America, though a few species have become naturalized in various parts of the Old World.

Nothoscordum is a conserved name. It´s synonymous with Pseudoscordum, which was described in 1837 by William Herbert as a reclassification of some Allium species. The term Nothoscordum comes from the fourth volume of Carl Sigismund Kunth´s work Enum. Pl., published six years later in 1843.

Species: Plants of the World Online accepts 91 species, although other authorities suggest only 20.
