Bungee cord is an elastic cord composed of one or more elastic strands forming a core, covered in a woven sheath usually of nylon or cotton. More recently, specialized bungee jumping cords are made entirely of elastic strands.

It is most often used to secure objects without tying knots or to absorb the shock of a suddenly applied load, as in bungee jumping or Dog sports such as Scootering.

Bungeecord is also used by the military to absorb the opening shock of the large cargo parachutes when dropping heavy loads such as tanks.
Bungeecord used for bungee jumping may have the ends bent around a non-metallic eye and wrapped with a strong, waxed string, called whipping, that is wound tightly while the cord is stretched.
Manufacturers of bungeecord for bungee jumping have their own standards which may include subjecting the cord to a number of full flex cycles and measuring the change in force versus extension to ensure the cord does not overextend.
