TBWA Worldwide is an international advertising agency whose headquarters are in Midtown Manhattan, New York City, United States. The Agency is a unit of Omnicom Group, the world's largest advertising agency holding company. It was founded in 1970 in Paris, France, by William G. Tragos (American, Management), Claude Bonnange (French, Marketing), Uli Wiesendanger (Swiss, Creation), and Paolo Ajroldi (Italian, Client Services). The first letter of each founder's name provided the initials for the new organization. They were purchased by the Omnicom Group in 1993.

During the 1990s Omnicom merged TBWA with other top creative agencies including Chiat/Day and Hunt Lascaris, building a network of creative agencies around the world. Over time it set up agencies in more and more markets, both through affiliations, joint ventures and wholly owned companies. It started to attract global clients who helped develop and strengthen its network.

In the United States, TBWA operates through TBWA\Chiat\Day, with offices in Los Angeles, New York and Nashville. In other parts of the world the company also operates under a mixed brand name such as TBWA Hunt Lascaris, a highly awarded agency based in South Africa, TBWA\CONCEPT UNIT, West Africa's most awarded creative agency, and TBWA\RAAD an emerging operation that spans the Middle East and North Africa.
