A cow blow horn, often referred to as a cow horn or cattle horn, is a natural or crafted horn that originates from bovine animals. Traditionally, these horns have been used for various purposes, including as musical instruments, signaling devices, or decorative items.

In agricultural settings, cow horns can be fashioned into blow horns, which produce distinct, resonant sounds when blown into. This sound was historically used by farmers and herders to communicate across distances, call livestock, or mark events.

Today, cow blow horns are sometimes used in cultural ceremonies, folk music, or as collectible artifacts. They are valued for their natural acoustic properties and unique, rustic appearance.

The size of these horns can vary, generally ranging from 12 to 17 inches in length. Non-polished horns showcase the raw texture and color variations of the natural material, providing a rugged aesthetic suitable for traditional use or decorative purposes. These sizes make them practical for playing, as well as for use in ceremonies or as unique home accents.
