The buntline hitch is a knot used for attaching a rope to an object. It is formed by passing the working end around an object, then making a clove hitch around the rope's standing part, taking care that the turns of the clove hitch progress towards the object rather than away from it. Secure and easily tied, the buntline hitch will jam when subjected to extreme loads. Given the knot's propensity to jam, it is often made in slipped form.

The buntline hitch, when bent to a yard, makes a more secure knot than two half hitches, but is more liable to jam. It differs from two half hitches in that the second half hitch is inside instead of outside the first one.

Simple and effective, the buntline hitch dates to the age of sail, when it was used to secure buntlines to the foot of the sails on square-rigged ships. That the buntline hitch was the preferred knot speaks to its security and reliability. Once set, repeated jerking and slatting tend to tighten it further rather than loosen it. Its compact size allowed the foot of the sail to be drawn up as closely as possible to the buntline deadeyes on top of the yard.

It has gained in popularity in recent years due to its performance in slippery modern synthetic lines.

The buntline hitch is useful for attaching lines to rings, eyes, posts, rods, and railings where a compact and secure knot is required. The non-slipped form is appropriate for moderate loads or where the knot will not need to be untied often. If heavily loaded it can be difficult or impossible to untie without the aid of a marlinspike.

The slipped form is more versatile and convenient when a secure temporary hitch is needed. For example, the slipped buntline hitch is an excellent choice to fasten a line to one side of a vehicle's luggage rack, with a trucker's hitch being used on the other side to tension the line over a load placed between them.
