"Camissonia", sometimes commonly known as sun cup or sundrop, is a genus of annual and perennial plants in the evening primrose family Onagraceae. A total of 62 species are known, nearly all from western North America, especially in the California Floristic Province, but also one from South America.

The flowers generally open at dawn, and may be yellow, white, or lavender, often with darker shades at the base. They are usually cup-shaped, thus the common name.

Formerly included in "Oenothera", the species of "Camissonia" are distinguished by having a club- or head-shaped stigma, instead of the 4-part-divided stigma of "Oenothera" or "Clarkia".

"Camissonia" species are used as food plants by the larvae of some Lepidoptera species including "Schinia cupes" and "Schinia deserticola", both of which feed on "C. claviformis", the latter exclusively.

The genus is named after the botanist Adelbert von Chamisso.
