The Ermenegildo Zegna Group is an Italian luxury group founded in 1910 in Trivero, Province of Biella, in Piedmont. It is led by the Zegna family and is one of the most well-known entrepreneurial realities in Italy on an international level. The group is considered a world leader in men's luxury fashion. Currently, 90% of its sales are covered by exports, with China as the primary market. As of 2021, the Group has over 500 stores in about 80 countries, of which 297 are directly managed.

Its first significant growth occurs in the post-war period thanks to exports to the United States and innovative marketing insights for the time, such as branding fabrics and advertising on trains.

Between the late sixties and the seventies, the company internationalizes: production expands to Spain, Germany, Austria, Switzerland, France, Greece, Turkey, and Mexico.

In 1980, in Paris, Zegna opens its first mono-brand boutique, followed five years later by the one in Milan. Starting in the nineties, a strategy of vertical integration and further brand expansion begins, also through a long series of acquisitions and partnerships.

The group is particularly active in corporate social responsibility, which began in the 1930s when the founder distinguished himself by promoting a series of socio-assistance works for the Trivero community.

Since December 2021, the company has been listed on the NYSE of the New York Stock Exchange.
