Thelypodium crispum is a species of flowering plant in the mustard family known by the common name crisped thelypody.

[1] It is native to the mountains and plateaus of Nevada and eastern California, where it grows in areas with mineral-rich and alkaline soils, such as the margins of hot springs.

Thelypodium crispum is an annual, biennial, or short-lived perennial herb producing an erect, branching stem to a maximum height anywhere between 10 centimeters and 1.2 meters.

The inflorescence is a dense, spikelike raceme of many white, greenish, or lavender flowers with very crinkly petals.

The fruit is a cylindrical silique 1 to 2.5 centimeters long with several seeds inside.
