The khukuri (Nepali: खुकुरी) is a Nepalese knife with an inwardly curved edge, used as both a tool and as a weapon in Nepal and neighboring countries of South Asia. Traditionally it was, and in many cases still is, the basic utility knife of the Nepalese people. It is a characteristic weapon of the Nepalese Army, the Royal Gurkha Rifles and of all Gurkha regiments throughout the world, so much so that many English-speakers refer to the weapon as a "Gurkha blade" or "Gurkha knife". The kukri often appears in Nepalese heraldry and is used in many traditional rituals such as wedding ceremonies.

The "kukri" and "kukkri" spellings are of Western origin, the original Nepalese form being khukuri.
