HSBC Bank USA, National Association, an American subsidiary of the British banking group HSBC, is a bank with its operational head office in New York City and its nominal head office in Tysons, Virginia (as designated on its charter). HSBC Bank USA, N.A. is a national bank chartered under the National Bank Act, and thus is regulated by the Office of the Comptroller of the Currency (OCC), a part of the U.S. Department of the Treasury.

Although this company was established in 1850 as Marine Midland Bank, its presence dates to 1865 when HSBC entered into the American market by opening an office in San Francisco before becoming a branch in 1875. Through multiple expansions nationwide and the full acquisition of Marine Midland in 1987, the company adopted its current HSBC USA name in 1999.

The company has 22 branch locations, down from the previous 148 before divesting its retail banking business to Citizens Financial Group, Cathay Bank and KeyBank in 2021.

The Hongkong and Shanghai Banking Corporation began its presence into the United States market in 1865 when it opened an office in San Francisco, California. That office became a full-fledged branch in 1875 and in 1880, the bank opened its first East Coast branch in New York City.

In 1980, HSBC acquired a 51% controlling interest in Marine Midland Bank, headquartered in Buffalo, New York. The bank's roots had dated to 1850. HSBC acquired the remaining interest in 1987.

At the same time, HSBC transferred 2 branches in the northwestern United States to HSBC Bank Canada. The next year, Marine completed its acquisition of First Federal Savings and Loan from Toronto-based Canada Trust, for $620 million.
