Astragalus bicristatus is a species of milkvetch known by the common names crested milkvetch and two-crested milkvetch. It is endemic to southern California, where it grows in the coniferous forests of the San Gabriel and San Bernardino Mountains of the Transverse Ranges.
Astragalus bicristatus is a perennial herb sprawling outwards with stems to a maximum length approaching half a meter. The leaves are up to 14 centimeters long and are made up of very widely spaced narrow linear leaflets. The stems and foliage have sparse grayish hairs, giving them a rough texture. The inflorescence is a loose array of up to 20 pealike flowers. Each flower is between 1 and 2 centimeters long and is purple-tinted white to light greenish yellow.
The fruit is a hanging capsule 2 to 4 centimeters long and curved or crescent-shaped. It is fleshy when immature and leathery to woody when dried.
