Atlantic National Bank was a bank located at 17 Nassau Street in lower Manhattan in New York. It was organized in 1853 as a state institution. It became a national bank after legislation authorizing such institutions was voted on by the United States Congress. It was selected by the Erie Canal Board as a depository of its canal tolls in March 1856. The bank became insolvent in April 1873.

The Atlantic National Bank was one of three in New York City to be exempted from taxes which pertained to capital invested in United States stocks after February 25, 1862. On that date a clause in an act was passed specifying this exclusion. The amount which the Atlantic National Bank declined to pay was $5,203.20.

In April 1864 an amendment was passed in the New York Legislature to amend the bank's charter. In December 1865 the bank's directors declared a semi-annual 6% dividend which was exempt from government tax. The funds to be issued came from the profits of the previous six months. They were distributed after January 2, 1866. J. E. Southworth was the bank's president at the time. Read more at https://en.wikipedia.org/wiki/Atlantic_National_Bank_(New_York_City)
