A rope is a length of fibers, twisted or braided together to improve strength, for pulling and connecting. It has tensile strength but is too flexible to provide compressive strength (i.e., it can be used for pulling, not pushing). Common materials for rope include manila, hemp, hair, nylon, and steel. Sometimes woven straps or chains are used where rope could be used, especially in securing loads to vehicles.

Other fibrous plant materials sometimes used include cotton, linen, coconut-husk fiber (coir), jute, and sisal. Other synthetic fibers in use include various forms of polypropylene, polyethylene (e.g. Spectra ® a high modulus polyethylene), aramid (e.g. Kevlar ®), and polyester (e.g. Dacron ®). Some ropes are constructed of mixtures of several fibers or use co-polymer (mixed) fibers.

Rope has been an essential tool since prehistoric times. Today, steel wire rope has largely supplanted fiber rope in heavy construction and industrial applications because of higher tensile strength. Fiber rope is still used extensively in light industry and in activities like sailing and climbing.

In order to fasten ropes, a large number of knots are used. Some rope material, like hemp, is stronger when wet with water.

A pulley is used to convert the pulling force to another direction, and multiple pulleys may be used to increase the mechanical advantage, allowing the pulling or lifting of heavy loads with limited force and strength of rope. Winches and capstans are machines designed to pull ropes.
