A smoker is a type of outdoor cooking device that cooks food slowly using smoke from burning wood. A smoker keeps the temperature low and steady for hours, letting smoke flavor meat like brisket or ribs. Pitmasters (people who specialize in this cooking style) take great pride in their smokers, carefully choosing woods like hickory or mesquite that give different flavors. Some competition barbecue teams spend years perfecting their technique with their smokers.

Smoker can also mean a person who smokes tobacco, although this is less common than it used to be.
