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 also applied to oolong or green teas, including white tea, and tisanes, such as rooibos, that contain oil of bergamot, or a bergamot flavour.

Because of Earl Grey's aroma and Twinings' distinctive packaging in England with Charles Grey, 2nd Earl Grey, the tea is sometimes called "Old Stinky".

Earl Grey tea is available in full flavor and in decaffeinated loose leaf.
