Horn or Horns may refer to:

• Horn (anatomy), a pointed, bony projection on the head of various animals (that of a rhinoceros) ; source of most other uses below
• Horn, see keratin, the substance that, apart from other functions, is the main component of the tissue that sheaths the bony core of horns and hoofs of various animals

A horn is a permanent pointed projection on the head of various animals consisting of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct to antlers which are not permanent. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae ( pronghorn) and Bovidae ( cattle, goats, antelope etc.).

One pair of horns is usual; however, two or more pairs occur in a few wild species and domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro.

Horns usually have a curved or spiral shape, often with ridges or fluting. In many species only males have horns. Horns start to grow soon after birth, and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core). Partial or deformed horns in livestock are called scurs. Similar growths on other parts of the body are not usually called horns, but spurs, claws or hoofs depending on the part of the body on which they occur.

The horn ( or ) is a diacritic mark attached to the top right corner of the letters o and u in the Vietnamese alphabet to give ơ and ư, unrounded variants of the vowel represented by the basic letter. In Vietnamese, it is rarely considered a separate diacritic; rather, the characters ơ and ư are considered separate from o and u.

The Horn mansion (角宿, pinyin: Jiǎo Xiù) is one of the Twenty-eight mansions of the Chinese constellations. It is one of the eastern mansions of the Azure Dragon.

An acoustic horn or waveguide is a tapered sound guide designed to provide an acoustic impedance match between a sound source and free air. This has the effect of maximizing the efficiency with which sound waves from the particular source are transferred to the air. Conversely, a horn can be used at the receiving end to optimize the transfer of sound from the air to a receiver.

Acoustic horns are found in nature in the form of the burrows constructed by male mole crickets to amplify their song.

Horn is an iOS and Android game developed by Phosphor Games Studio and published by Zynga on August 16, 2012.

The River Horn ( French: La Horn; German: Hornbach) is a left tributary of Schwarzbach flowing through the region of Lorraine, in north-east France, and the state of Rhineland-Palatinate, in southern Germany. Its headwaters rise in the French town of Bitche, in the Moselle Department, following a north by north-eastern course, before forming a part of the border between France and Germany. As the Franco-German border takes a sharp turn to the west, the Horn continues into Germany. Here, it follows a roughly north-western course, ending in the German town of Zweibrücken, emptying into the Schwarzbach. Its length in France is 27.6 km.

A horn is any of a family of musical instruments made of a tube, usually made of metal and often curved in various ways, with one narrow end into which the musician blows, and a wide end from which sound emerges. In horns, unlike other brass instruments such as the trumpet, the bore gradually increases in width through most of its length—that is to say, it is conical rather than cylindrical. In jazz and popular-music contexts, the word may be used loosely to refer to any wind instrument, and a section of brass or woodwind instruments, or a mixture of the two, is called a horn section in these contexts.
