Dao are single-edged Chinese swords, primarily used for slashing and chopping. The most common form is also known as the Chinese sabre, although those with wider blades are sometimes referred to as Chinese broadswords. In China, the dao is considered one of the four traditional weapons, along with the gun (stick or staff), qiang (spear), and the jian (sword). It is considered "The General of All Weapons".

In Chinese, the word can be applied to any weapon with a single-edged blade and usually refers to knives. Because of this, the term is sometimes translated as knife or sword-knife. Nonetheless, within Chinese martial arts and in military contexts, the larger "sword" versions of the dao are usually intended.

While dao have varied greatly over the centuries, most single-handed dao of the Ming period and later, and the modern swords that are based on them share a number of characteristics. Dao blades are moderately curved and single-edged, though often with a few inches of the back edge sharpened as well; the moderate curve allows them to be reasonably effective in the thrust. Hilts are sometimes canted, curving in the opposite direction as the blade which improves handling in some forms of cuts and thrusts. Cord is usually wrapped over the wood of the handle. Hilts may also be pierced like those of jian (straight-bladed Chinese sword) for the addition of lanyards, though modern swords for performances will often have tassels or scarves instead. Guards are typically disc-shaped often with a cupped shape to prevent rainwater from getting into the sheath, and to prevent blood from dripping down to the handle, making it more difficult to grip. Sometimes guards are thinner pieces of metal with an s-curve, the lower limb of the curve protecting the user's knuckles; very rarely they may have guards like those of the jian.
