Salomon Brothers, Inc., was an American multinational bulge bracket investment bank headquartered in New York City. It was one of the five largest investment banking enterprises in the United States and a very profitable firm on Wall Street during the 1980s and 1990s. Its CEO and chairman at that time, John Gutfreund, was nicknamed "the King of Wall Street".

Bulge bracket banks are the world's largest global investment banks, serving mostly large corporations, institutional investors and governments. The term "Bulge Bracket" comes from the way investment banks are listed on the "tombstone", or public notification of a financial transaction, where the largest advisors on investment banking operations are listed first. The term is primarily related to the financial advisory side of the business, as opposed to sales and trading.
