Clogging is a type of folk dance that originated in the Appalachian Mountains of the United States. It is characterized by the percussive use of the dancers footwear, striking the heel, the toe, or both against a floor or each other to create audible rhythms, usually to the downbeat with the heel keeping rhythm. Clogging is associated with the predecessor to bluegrass music, "old-time" music, which is based on English, Irish, and African American banjo tunes. The dance form primarily developed from Irish step dancing called Sean-nós dance, as well as English, Scottish, German, and Cherokee step dances, as well as African rhythms and movement influences. It was from clogging that tap dance eventually evolved.

Clogging is the official state dance of Kentucky and North Carolina. The dance form is a means of personal expression and has been passed down through generations. Traditional Appalachian clogging is characterized by loose, often bent knees and a "drag-slide" motion of the foot across the floor, and is usually performed to old-time music.

Clogging has evolved over time, and contemporary clogging incorporates other forms of dance and a variety of music. Competition clogging has picked up in the twentieth and twenty-first centuries, leading to more innovation in style and a greater focus on performance. Although the setting for clogging has evolved, the practice has been passed down through generations, and improvisation and modernization of the steps are tethered to traditional steps and movements.
