M-Market is a Finnish grocery store chain. The chain was founded by independent retailers in 2006, which was created as a result of cooperation between retailers who opposed the sale of Spar Finland to SOK and resigned from the chain. The M-chain's grocery sales (incl. consumer goods) were approximately EUR 98 million in 2015, when the chain's market share of the Finnish grocery trade was estimated at a total of 0.6%. The M-chain's stores are approximately 200–2,500 m2 in size.
