Tesco plc (/ˈtɛs.koʊ/) is a British multinational groceries and general merchandise retailer headquartered in the United Kingdom at its head offices in Welwyn Garden City, England. The company was founded by Sir Jack Cohen in Hackney, London, in 1919. In 2023, it was the 15th largest retailer in the world by revenue. It is the market leader of groceries in the UK (where it has a market share of around 28.4%). Tesco also has stores in the Czech Republic, Ireland, Slovakia, the Isle of Man and Hungary.
Since the 1960s, Tesco has diversified into areas such as the retailing of books, clothing, electronics, furniture, toys, petrol, software, financial services, telecommunications and internet services. In the 1990s, Tesco re-positioned itself from being a downmarket high-volume low-cost retailer, attempting to attract a range of social groups with its low-cost "Tesco Value" range (launched 1993) and premium "Tesco Finest" range.
Tesco is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
