Earl Grey tea is a tea blend with a distinctive flavour and aroma derived from the addition of oil extracted from the rind of the bergamot orange, a fragrant citrus fruit.

Traditionally the term "Earl Grey" was applied only to black tea; however, today the term is used for other teas that contain oil of bergamot, or a bergamot flavour.

The Earl Grey blend is named after the 2nd Earl Grey, British Prime Minister in the 1830s and author of the Reform Bill of 1832, who reputedly received a gift, probably a diplomatic perquisite, of tea flavoured with bergamot oil, taken from bergamot, a citrus fruit typical of Southeast Asia and grown commercially in Italy.
