Mead (), also called hydromel, particularly when low in alcohol content, is an alcoholic beverage made by fermenting honey mixed with water, and sometimes with added ingredients such as fruits, spices, grains, or hops. The alcoholic content ranges from about 3.5% ABV to more than 20%. The defining characteristic of mead is that the majority of the beverage's fermentable sugar is derived from honey. It may be still, carbonated, or naturally sparkling; dry, semi-sweet, or sweet.

The term honey wine is sometimes used as a synonym for mead, although wine is typically defined to be the product of fermented grapes or certain other fruits, and some cultures have honey wines that are distinct from mead. The honey wine of Hungary, for example, is the fermentation of honey-sweetened pomace of grapes or other fruits.

Mead was produced in ancient times throughout Europe, Africa, and Asia, and has played an important role in the mythology of some peoples. In Norse mythology, for example, the Mead of Poetry, crafted from the blood of Kvasir (a wise being born from the mingled spittle of the Aesir and Vanir deities) would turn anyone who drank it into a poet or scholar.
