Stenanthium is a North American genus of flowering plants in the tribe Melanthieae of the family Melanthiaceae.

[2] Molecular phylogenetic studies in the 21st century have resulted in number of changes to placements within this tribe.

Members of Stenanthium, as currently circumscribed, may also be distinguished from other deathcamases by having a slender cylindrical bulb and the lack of sarcotesta on its brown seeds.

[14][15][16][17] The World Checklist of Selected Plant Families recognized three species in 2013, treating S. leimanthoides as a synonym of S. densum.

[18] Research by Sorrie and Weakley (2017) described two new species of Stenanthium in the southeastern United States: S. macrum and S.
