Regis Corporation is an American operator of hair salons, and the largest such chain in the world, with over 10,000 salons (both company-owned and franchises). It has its headquarters in Saint Louis Park, Minnesota. 

Regis owns the brands Supercuts (located in strip malls), SmartStyle (located in Walmart stores), MasterCuts (located in shopping malls), Regis Salons, Sassoon Salons, Cost Cutters and First Choice Haircutters, as well as several smaller or regional brand "concepts."

Regis is based in Saint Louis Park, Minnesota and was founded in 1922 by Paul and Florence Kunin as Kunin Beauty Salon, and renamed Regis in 1958 by their son Myron who acquired the chain.

Regis acquired a major competitor The Barbers, Hairstyling for Men & Women, Inc., which had previously brought the companies: The Cost Cutters, Family Hair Care, City Looks Salons International and We Care Hair. Other major acquisitions included Sassoon and HCUK. Regis sells Designline hair care products (2004) as well.
