The buk (Korean: 북) is a traditional Korean drum. While the term buk is a native Korean word used as a generic term meaning "drum", it is most often used to refer to a shallow barrel-shaped drum, with a round wooden body that is covered on both ends with animal skin. Buk are categorized as hyeokbu which are instruments made with leather, and has been used for jeongak and folk music.

The drum is a member of the percussion group of musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a percussion mallet, to produce sound. There is usually a resonant head on the underside of the drum. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.
