Barra Airport (also known as Barra Eoligarry Airport) is a short-runway airport (or STOLport) situated in the wide shallow bay of Traigh Mhòr at the northern tip of the island of Barra in the Outer Hebrides, Scotland.

The airport is unique, believed to be the only one in the world where scheduled flights use a tidal beach as the runway. The airport is operated by Highlands and Islands Airports Limited, which owns most of the regional airports in mainland Scotland and the outlying islands. Barra Airport opened in 1936. The airport’s only destination is Glasgow.

The beach is set out with three runways, marked by wooden poles at their ends. This allows the Twin Otters that serve the airport to almost always land into the wind. At high tide, these runways are under the sea, and flight times have to be regularly rescheduled with the tide. If an emergency night landing is required, vehicle lights are used to illuminate the runway, and reflective strips are laid on the beach.
