The 77 Bank, Ltd. (株式会社七十七銀行, Kabushiki-gaisha Shichijūshichi Ginkō) (TYO: 8341) is a Japanese regional bank headquartered in Sendai, Miyagi Prefecture.

As the designated financial institution of the prefecture, the city, and many other cities and towns throughout the prefecture, it performs duties such as holding deposits for public money and handling payments.

Following criticism for lagging behind in the establishment of a cooperative ATM network, the bank is scheduled to enter into an agreement with two other convenience store operators within the prefecture in March, 2006.

Having received approval from the Ministry of Finance in February, 1878, The 77th National Bank was established in September in Miyagi prefecture, an area with very limited banking services at the time.

Although The 77 Bank closed representative offices and branches in London and New York City after the collapse of the bubble economy in the 1990s, it opened a representative office in Shanghai in July, 2005.
