|synonyms ref = is a small genus of aromatic evergreen shrubs in the rue family, Rutaceae. Members of the genus are commonly known as Mexican orange due to the similarity of their flowers to those of the closely related orange, both in shape and scent. They are native to southern North America, from Arizona, New Mexico, Texas and south through most of Mexico. In its generic name Humboldt and Bonpland honoured Swiss botanist Jacques Denis Choisy (1799–1859).

The species grow to tall. The leaves are opposite, leathery, glossy, palmately compound with 3 13 leaflets, each leaflet long and broad. C. ternata has three broad leaflets, while C. dumosa has up to 13 very narrow leaflets. The flowers are star shaped, diameter, with 4 7 white petals, 8 15 stamens and a green stigma; they are produced throughout the late spring and summer. The fruit is a leathery two to six sectioned capsule.

Many quinoline alkaloids have been isolated from leaves of Choisya ternata. C. ternata contains an alkaloid (ternanthranin), a volatile simple anthranilate that can be considered responsible for the antinociceptive activity of the crude plant extracts.

Choisya can be prone to attack by pythium root rot, particularly when propagated and grown in pots for the horticultural trade. In north west Europe the main pest is snails, which eat the bark of even mature specimens, resulting in minor die back of branches where ring barking has occurred.
