''Citrus bergamia'', the bergamot orange (pronounced ), is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness.
Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Extracts have been used as an aromatic ingredient in food, tea, snus, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure.

Taxonomy
The bergamot orange is unrelated to the herbs known as bergamot, wild bergamot, bergamot mint, or bergamint – '' Monarda didyma'', '' Monarda fistulosa'', and Eau de Cologne mint (the taxonomy of which is disputed). Those are all in the mint family, and are named for their similar aroma.

As of 2017, clinical research conducted on bergamot oil has been of poor quality, with no conclusions about its possible biological effects. Consuming bergamot oil as a component of tea may cause muscle cramps. Use on the skin may be unsafe, particularly for children and pregnant women, and may cause rashes resulting from photodermatotoxicity.
