bichuwe) (Hindi: बिछुवा, Urdu: بچھوا) is a dagger, originating from the Indian subcontinent, with a loop hilt and a narrow undulating sharp blade.

The bichuwa usually has a narrow recurved blade and a simple looped handle which may be cut with chevrons.

Medieval bichuwa from south India are typically decorated with the face of a protective yali (demon) on the hilt.

The weapon's small size meant it was easily concealed in a sleeve or waist band.

This combination weapon, known as a bichuwa bagh naka, was used by the Maratha leader Chhatrapati Shivaji Maharaj to assassinate Afzal Khan in the 17th century.
