彩虹菊（学名：Dorotheanthus bellidiformis）为菊科彩虹菊属下的一个种。

Dorotheanthus bellidiformis, commonly called Livingstone daisy, Bokbaaivygie (Afrikaans), or Buck Bay vygie, is a species of flowering plant in the family Aizoaceae, native to the Cape Peninsula in South Africa. It is a low-growing succulent annual growing to 25 cm (10 in), and much cultivated for its iridescent, many-petalled, daisy-like blooms in shades of white, yellow, orange, cream, pink and crimson. In temperate areas it must be grown as a half-hardy annual, and lends itself to mass plantings or as edging plants in summer bedding schemes in parks and gardens. It is still widely referenced under its former name, Mesembryanthemum criniflorum.
