Astragalus drummondii is a species of flowering plant in the legume family known by the common name Drummond's milkvetch.

Upon the return of samples collected by Drummond to England, his findings were published in Sir William Hooker’s Flora Boreali-Americana in 1840.

[2] Astragalus drummondii is found widely across the American west and Saskatchewan, Alberta, and British Columbia.

Individuals of this species are herbaceous perennial plants with thick, hairy stems as well as long-hairy foliage.

Samples of A. drummondii in New Mexico were tested and found to be negative for the production of swainsonine, suggesting that this species may be safe for cattle to eat.
