Deloitte is a multinational professional services network based in London, England. It is the largest professional services network in the world by revenue and number of employees, and is one of the Big Four accounting firms, along with EY, KPMG, and PwC.

It merged with Haskins & Sells to form Deloitte Haskins & Sells in 1972 and with Touche Ross in the US to form Deloitte & Touche in 1989. In 1993, the international firm was renamed Deloitte Touché Tohmatsu, later abbreviated to Deloitte. In 2002, Arthur Andersen's practice in the UK as well as several of that firm's practices in Europe and North and South America agreed to merge with Deloitte.
