Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae.

Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries.

Like many plants in the Solanaceae, Iochroma species contain phytochemicals with potential pharmaceutical value but the genus has not been exhaustively studied in this respect.

Iochroma fuchsioides is taken by the medicine men of the Kamsa Indians of the Sibundoy valley in the Colombian Andes for difficult diagnoses, the unpleasant side effects lasting several days.

[2][3] As of February 2023[update], Acnistus, previously treated as a separate genus, was regarded as a synonym of Iochroma.
