Can refer to a number of things:
- An accessory worn in the hair or upon clothing. Usually a ribbon, tied in a bow knot
- A projectile weapon that predates recorded history and is common to most cultures. A bow is a flexible arc that shoots aerodynamic projectiles (arrows or quarrels, sometimes stones) by means of elastic energy. Essentially, the bow is a form of spring powered by a string or cord. As this string is drawn, energy is stored in the flexible limbs of the bow; the energy is transferred to the arrow when the string is released, projecting it much farther than a weapon could be thrown.
- In music, a bow is moved across some part of a musical instrument, causing vibration which the instrument emits as sound. The vast majority of bows are used with string instruments, although some bows are used with musical saws and other bowed idiophones.
