Calochortus elegans is a species of flowering plant in the lily family known by the common name elegant Mariposa lily, cat's ear, elegant cat's ears or star tulip. It is native to the western United States from northern California to Montana.

It is a perennial herb producing a slender, generally unbranched stem up to 15 centimeters in height. The basal leaf is 10 to 20 centimeters long and does not wither at flowering. The inflorescence bears 1 to 7 erect bell-shaped flowers. Each flower has three sepals and three petals with very hairy inner surfaces and edges. Each petal is greenish white in color with a purple crescent above a hairless patch at the base. The fruit is a winged capsule about 2 centimeters long.

The bulb is a choice wild root vegetable when eaten cooked, and can be eaten raw to avoid starvation. It grows in open woodland and grassy hillsides.
