"St. Michael" is a brand name with a long and storied history, primarily known for its association with the British retailer Marks & Spencer.

From 1927 until 2000, "St. Michael" was the flagship brand for almost all goods sold by Marks & Spencer, including clothing, food, and home furnishings. The brand's identity was built on a promise of quality, reliability, and value. For decades, it was a trusted name that was synonymous with the Marks & Spencer experience. The name itself was a tribute to Michael Marks, one of the company's founders.

In 2000, as part of a major rebranding effort, Marks & Spencer decided to drop the "St. Michael" name from most of its products to modernize its image and focus on the M&S brand. However, due to its nostalgic appeal, the "St. Michael" name has seen a resurgence in vintage clothing markets and has been brought back by Marks & Spencer in recent years for specific product lines, particularly within its clothing range, to capitalize on the brand's enduring heritage and reputation for classic quality.
