Cross listing of shares is when a firm lists its equity shares on one or more foreign stock exchange in addition to its domestic exchange. Examples include: American Depositary Receipt (ADR), European Depositary Receipt (EDR), International Depositary Receipt (IDR) and Global Registered Shares (GRS).

Generally such a company's primary listing is on a stock exchange in its country of incorporation, and its secondary listing(s) is on an exchange in another country. Cross-listing is especially common for companies that started out in a small market but grew into a larger market. For example, numerous large non-U.S. companies are listed on the New York Stock Exchange or NASDAQ as well as on their respective national exchanges such as Enbridge, BlackBerry Ltd, Statoil, Ericcson, Nokia, Toyota and Sony.
