Stone & Webster was an American engineering services company based in Stoughton, Massachusetts. It was founded as an electrical testing lab and consulting firm by electrical engineers Charles Stone and Edwin S. Webster in 1889. In the early 20th century, Stone & Webster was known for operating streetcar systems in many cities across the United States; examples include Dallas, Houston and Seattle. The company grew to provide engineering, construction, environmental, and plant operation and maintenance services, and it has long been involved in power generation projects, and with most American nuclear power plants.

Stone & Webster was acquired and integrated as a division of The Shaw Group in 2000, and in 2012, the French engineering conglomerate Technip acquired Stone & Webster's energy and chemical business, and process technologies and associated oil and gas engineering capabilities from The Shaw Group. The CB&I acquisition of other assets of the The Shaw Group, also in 2012, resulted in the formation of a nuclear power subsidiary, CB&I Stone Webster, which operated for about 4 years, being sold in January 2016 to Westinghouse Electric.

Charles A. Stone and Edwin S. Webster first met in 1884 and became close friends while studying electrical engineering at the Massachusetts Institute of Technology. In 1890, only two years after graduating, they formed the Massachusetts Electrical Engineering Company. The name was changed to Stone & Webster in 1893. Their company was one of the earliest electrical engineering consulting firms in the United States.
