A ball-jointed doll is any doll that is articulated with ball and socket joints. In contemporary usage when referring to modern dolls, and particularly when using the acronyms BJD or ABJD, it usually refers to modern Asian ball-jointed dolls. These are cast in polyurethane synthetic resin, a hard, dense plastic, and the parts strung together with a thick elastic. They are predominantly produced in Japan, South Korea and China. The BJD style has been described as both realistic and influenced by anime. They commonly range in size from about for the larger dolls, for the mini dolls, and all the way down to the very smallest BJDs. BJDs are primarily intended for adult collectors and customizers.

During the 1930s, the German artist Hans Bellmer created dolls with ball-joints and used them in photography and other surrealistic artwork. Bellmer introduced the idea of artful doll photography, which continues today with Japanese doll artists, as well as BJD hobbyists. Influenced by Bellmer and the rich Japanese doll tradition, Japanese artists began creating strung ball-jointed art dolls. These are commonly made entirely of bisque and often very tall, sometimes as tall as . These dolls are purely intended as art, and not for play or even the hobby level of collecting usually associated with dolls. They cost several thousand dollars, up to several hundred thousand dollars for older collectible dolls from famous artists. The art doll community is still active in Japan and artists regularly release artbooks with photographs of their dolls. The history of commercially produced Asian resin BJDs began in 1999 when the Japanese
