Dixons Retail plc was one of the largest consumer electronics retailers in Europe, which merged with Carphone Warehouse in 2014 to create Dixons Carphone, which was renamed Currys plc in 2021. In the United Kingdom, the company operated Currys, Currys Digital, PC World (with stores increasingly dual-branded Currys PC World), Dixons Travel and its service brand Knowhow.

At the time of the merger in 2014, Dixons Retail had 530 outlets in the United Kingdom and Ireland and 322 in Northern Europe. Its Nordic and central European business was operated under the Elkjøp umbrella, and it also operated Kotsovolos in Greece. The company was listed on the London Stock Exchange and was a constituent of the FTSE 250 Index.

The company, formerly known as Dixons Group plc and later DSG International plc, specialised in selling mass market technology consumer electronics products, audio video equipment, PCs, small and large domestic appliances, photographic equipment, communication products and related financial and after-sales services such as extended service agreements, product set-up and installation, and repairs.

Dixons was founded as a photographic studio by Charles Kalms and Michael Mindel in High Street in Southend under the name of Dixons Studios Limited, a company registered in October 1937 with a share capital of £100. The name Dixons, selected randomly from the telephone directory, was sufficiently short to fit above the small shop front. In the early 1940s, Dixons set up seven studios around London but by the end of the Second World War the business had been reduced to a single studio in Edgware. Stanley Kalms, the son of the founder, joined the business in 1948 and started advertising direct sales in the press, with postal ordering and delivery.

In 1950, the company began to sell cameras. In 1957, it opened a head office to house the staff now dealing with 60,000 mail order customers and to centralise buying.

Dixons was first listed on the London Stock Exchange in 1962, changing its name at that time to Dixons Photographic Limited. It bought out competitors Ascotts in 1962, and Bennetts in 1964. In 1967, Dixons bought an 85,000 sq ft (7,900 m²) colour film processing laboratory in Stevenage. Charles Kalms was succeeded by his son Stanley in 1971. In 1972, Dixons bought another competitor, Wallace Heaton, and in 1974, it opened its Stevenage distribution centre.

In 1984 Dixons acquired Currys, a retail chain with 570 shops selling electrical and other household goods; Currys retained its separate brand identity.

In February 1993, Dixons bought Vision Technology Group (VTG), operating under the PC World brand at Croydon, Lakeside Shopping Centre, Brentford and Staples Corner. Later that year, the company sold VTG's mail order division, Dixons US Holdings Inc and Supasnaps. The company opened its first duty free store at Heathrow Terminal 3 in 1994, and later that year launched phone store The Link, the company's first venture into communications. The head office moved to Hemel Hempstead.
