The Croydon Co-operative Society was a cooperative retailer in Croydon and surrounding parts of Surrey, England. In 1918, it became part of the new South Suburban Co-operative Society, now the Co-operative Group. A co-operative society had been formed in Croydon in 1860, the Croydon Co-operative Industrial Society, with headquarters in Market Street and later at 39 Church Street. However, after several years of good progress, the Society went into voluntary liquidation in March 1874.
