The baritone horn, sometimes called baritone, is 3 or 4 valved tenor-voiced brass instrument in the saxhorn family. It is a piston-valve brass instrument with a bore that is mostly conical, like the smaller and higher pitched flugelhorn and tenor horn, but it has a narrower bore compared to the similarly pitched euphonium. It uses a wide-rimmed cup mouthpiece like that of its peers, the trombone and euphonium. Like the trombone and the euphonium, the baritone can be considered either a transposing or non-transposing instrument.

In the UK, the baritone is part of the standardized instrumentation of brass bands. In concert band music, there is often a part marked baritone, but these parts are most commonly intended for, and played on, the euphonium. A baritone can also play music written for a trombone due to similarities in timbre and range.
