An American depositary receipt (ADR, and sometimes spelled depository) is a negotiable security that represents securities of a non-U.S. company that trades in the U.S. financial markets.

Shares of many non-U.S. companies trade on U.S. stock exchanges through ADRs, which are denominated and pay dividends in U.S. dollars and may be traded like regular shares of stock. ADRs are also traded during U.S. trading hours, through U.S. broker-dealers. They simplify investing in foreign securities by having the depositary bank "manage all custody, currency and local taxes issues".
