St Michael was a brand owned and used by British retailer Marks & Spencer between 1927 and 2000.

In 1875, the firm of N. Corah and Sons of Leicester registered "St Margaret" as a brand name for their hosiery products.

In order to protect their other distribution channels, Corahs sought to develop an alternative brand name for their goods sold through Marks & Spencer.

[1] At first it applied only to products produced by Corahs, but by 1950 and for the next fifty years, almost all goods sold by Marks & Spencer used the St Michael brand.

[1] For the next few years, the St Michael name was adopted as the 'St Michael Quality Promise' on the back of food products, on the side of delivery vehicles and on in-store receipts.
