The Brenner Pass is a mountain pass over the Alps which forms the border between Italy and Austria. It is one of the principal passes of the Eastern Alpine range and has the lowest altitude among Alpine passes of the area.

A mountain pass is a navigable route through a mountain range or over a ridge. Since mountain ranges can present formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind.
