Guinness Nigeria, a Nigerian-based subsidiary of Diageo Plc of the United Kingdom, was incorporated in 1962 with the building of a brewery in Ikeja.^[1] The brewery was the first Guinness operation outside Ireland and Great Britain. Other breweries have been opened over time: Ogba brewery in 1963 and Benin City brewery in 1973.

Guinness product was sold in Nigeria in the 1940s and 1950s by United Africa Company (UAC) and the country soon became an important export market for the firm. In 1961, plans came into fruition between Arthur Guinness Son and Co and UAC to establish a brewery at Ikeja, Lagos.^[2] Arthur Guinness first factory outside Ireland and the UK was built by Taylor Woodrow. The initial plant had the annual capacity to brew 75 million bottles or 150,000 barrels of beer. The plant area had a 15 million capacity bottle bin and office block designed by the firm of Godwin and Hopwood.^[3]
