An amphora (plural: amphorae or amphoras) is a type of vase-shaped, usually ceramic (specimens in materials such as metal occur occasionally) container with two handles and a long neck narrower than the body. The word amphora is Latin, derived from the Greek amphoreus (αμφορεύς), an abbreviation of amphiphoreus (αμφιφορεύς), a compound word combining amphi- ("on both sides", "twain") plus phoreus ("carrier"), from pherein ("to carry"), referring to the vessel's two carrying handles on opposite sides.

Further, the term also stands for an ancient Roman unit of measurement for liquids. The volume of a Roman amphora was one cubic foot, ca. 26,026 L.

Amphorae were used in vast numbers to transport and store various products, both liquid and dry, in the ancient Mediterranean world and later the Roman Empire, and in some periods the shape was also used for luxury pottery, which might be elaborately painted. Stoppers of perishable materials which have rarely survived were used to seal the contents. Two principal types of amphorae existed: the neck amphora, in which the neck and body meet at a sharp angle; and the one-piece amphora, in which the neck and body form a continuous curve. Neck amphorae were commonly used in the early history of ancient Greece but were gradually replaced by the one-piece type from around the 7th century BCE onwards. Most were produced with a pointed base to allow upright storage by being partly embedded in sand or soft ground. This also facilitated transport by ship, where the amphorae were tightly packed together, with ropes passed through their handles to prevent breaking or toppling during rough seas. In kitchens and shops amphorae could be stored in racks with round holes in them.
