EY,[6][7] previously known as Ernst & Young, is a British multinational professional services network based in London, United Kingdom.[8] Along with Deloitte, KPMG and PwC, it is one of the Big Four accounting firms. The EY network is composed of member firms of Ernst & Young Global Limited, a UK company limited by guarantee.[8]

EY is one of the largest professional services networks in the world.[9] It primarily provides assurance, tax, information technology services (including managed services in areas like Cybersecurity, Cloud, Digital Transformation and AI), consulting, and advisory services to its clients.[10]

Ernst & Young Global Limited operates as a network of member firms which are structured as separate legal entities in a partnership, which has 395,442 employees in over 700 offices in more than 150 countries.[11] The firm's current partnership was formed in 1989 by a merger of two accounting firms: Ernst & Whinney and Arthur Young & Co.[12] It was named Ernst & Young until a rebranding campaign officially changed its name to EY in 2013,[13] although this initialism was already used informally prior to its sanctioning adoption.

In 2023, EY was the seventh-largest privately owned organization in the United States,[14] and EY has for 25 years been continuously ranked on Fortune magazine's list of the 100 Best Companies to Work For, longer than any other accounting firm.[15] The firm has, however, repeatedly come under scrutiny for systemic issues in their training, hiring, and work culture.
