Quorn is a brand of meat substitute products, or the company that makes them. Quorn originated in the UK and is sold primarily in Europe, but is available in 14 countries. The brand is owned by parent company Monde Nissin.

Quorn is sold as both a cooking ingredient and as a meat substitute used in a range of prepackaged meals.

All Quorn foods contain mycoprotein as an ingredient, which is derived from the Fusarium venenatum fungus. In most Quorn products, the fungus culture is dried and mixed with egg albumen, which acts as a binder, and then is adjusted in texture and pressed into various forms. A vegan formulation also exists that uses potato protein as a binder instead of egg albumen.
