A drawstring (draw string, draw-string) is a string, cord, lace, or rope used to “draw” (gather, or shorten) fabric or other material. The ends of the drawstring may be tied to hold it in place (and/or simultaneously close an opening). Alternately, the drawstring may be kept drawn using a cord lock. Typically, the drawstring is loose when not being used, and tightened when needed during use.

A drawstring may be threaded through a hem or casing (a continuous tube of material) or laced through holes, which may be lined with eyelets. It may also be laced through loops attached to the material, in the same way that belt loops are. A very wide, flat drawstring becomes a belt.
