The Bergamot orange (Citrus bergamia or Citrus aurantium (bitter orange) ssp. bergamia) is a citrus fruit, small and roughly pear shaped. It is sour and its aromatic peel is used to produce an essential oil that is used in Earl Grey tea, in perfumery, and in aromatherapy to treat depression. It was a component of the original Eau de Cologne developed in Germany in the 17th century.

The fruit, produced in Italy, is a cross between the pear lemon and the Seville orange or grapefruit.

The Bergamot orange is unrelated to the herb of the same name.
