The Minch and Lower Minch form part of the Inner Seas off the West Coast of Scotland, as defined by the International Hydrographic Organization.

The Minch ranges from 20 to 45 miles (32 to 72 km) wide and is approximately 70 miles (110 km) long. It is believed to be the site of the biggest meteorite ever to hit the British Isles. The Lower Minch is about 15 miles (24 km) wide. In June 2010 Eilidh Macdonald became the first person to swim across it from Waternish Point on Skye to Rodel on Harris, in a time of 9.5 hours.
