The clove hitch is an ancient type of knot, made of two successive single hitches^[1]: 283 tied around an object. It is most effectively used to secure a middle section of rope to an object it crosses over,^[1]: 213 such as a line on a fencepost. It can also be used as an ordinary hitch, or as a binding knot, but it is not particularly secure in either application.^{[1]: 18, 224} It is considered one of the most important knots, alongside the bowline and the sheet bend.

Although the name clove hitch is given by Falconer in his Dictionary of 1769, the knot is much older, having been tied in ratlines at least as early as the first quarter of the sixteenth century. This is shown in early sculpture and paintings. A round turn is taken with the ratline and then a hitch is added below. The forward end is always the first to be made fast.
