Arup, officially Arup Group Limited, is a British multinational professional services firm headquartered in London that provides design, engineering, architecture, planning, and advisory services across every aspect of the built environment. It employs about 17,000 people in over 90 offices across 35 countries, and has participated in projects in over 160 countries.

Arup was established in 1946 by Sir Ove Arup as Ove N. Arup Consulting Engineers. Through its involvement in high-profile projects such as the Sydney Opera House, it became well known for undertaking complex and challenging projects. In 1970, Arup stepped down from actively leading the company, setting out the principles which have continued to guide its operation. Arup's ownership is structured as a trust, whose beneficiaries are its employees, past, and present who receive a share of its operating profit each year.
