Founded in May 1888 as the Bank of Hannibal, HNB Bank, n.a., boasts a rich heritage rooted in community, integrity, and steadfast financial service. Our historic headquarters-constructed in 1889 on the corner of Main & Broadway in Hannibal, Missouri-still stands as a symbol of our enduring commitment. In 1903, the bank secured a national charter and adopted the name Hannibal National Bank, marking the beginning of expanded services across Northeast Missouri.

Over more than a century of growth and evolution, we embraced a broader identity in 2003, becoming HNB National Bank to reflect our expanding market reach. Today, we are proud to combine our long-standing traditions with modern banking solutions, serving businesses, families, and individuals with trustworthy guidance and local expertise. At HNB, our legacy isn’t just in our history-it’s in every customer relationship we build and maintain.
