Gamochaeta stagnalis, the Desert cudweed, is a species of flowering plant in the sunflower family. It is native to Mexico, Guatemala, and the southwestern United States (California, Arizona, New Mexico).

Gamochaeta stagnalis is an annual herb up to 35 cm (14 in) tall, producing a slender taproot. Leaves are up to 3 cm (1.2 in) long. The plant forms many small flower heads in tightly packed clumps. Each head contains 3-4 purple disc flowers but no ray flowers.

Gamochaeta stagnalis is very similar to G. purpureum and some G. stagnalis specimens (especially from Arizona) have been misidentified as that species.
