Glomel (French pronunciation: [ɡlɔmɛl]; Breton: Groñvel) is a commune in the Côtes-d'Armor department in Brittany in northwestern France.

Inhabitants of Glomel are called glomelois in French.

Glomel is located on the northern slope of the Montagnes Noires (french, Black Mountains).

This unique mineral, prized for its high-temperature resistance, has been extracted at the Guerphalès mine since 1970.

The site, operated by Imerys, plays a crucial role in the global andalusite market, producing 65,000 tonnes annually, which accounts for 20-25% of global output.
