A lur is a long natural blowing horn without finger holes that is played by embouchure. Lurs can be straight or curved in various shapes. The purpose of the curves was to make long instruments easier to carry (e.g. for marching, like the modern sousaphone) and to prevent directing the loud noise at nearby people.

The name lur is particularly given to two distinct types of ancient wind instruments. The more recent type is made of wood and was in use in Scandinavia during the Middle Ages. The older type, named after the more recent type, is made of bronze, dates to the Bronze Age and was often found in pairs, deposited in bogs, mainly in Denmark and Germany. It consists of a mouthpiece and several pieces and/or pipes. Its length can reach between 1.5 meters and 2 meters. It has been found in Norway, Denmark, South Sweden, and Northern Germany. Illustrations of lurs have also been found on several rock paintings in Scandinavia.

A total of 56 lurs have been discovered: 35 (including fragmentary ones) in Denmark, 4 in Norway, 11 in Sweden, 5 in northern Germany, and a single one in Latvia.
