Banco Colombiano was a private commercial bank based in Medellín, operating during the era of free banking in Colombia when the 1880 banking law permitted chartered institutions to issue their own currency. The American Bank Note Company produced notes for dozens of Latin American issuers during this period, and the Colombian private bank series represents some of the more obscure work in their catalog — fewer surviving examples exist compared to the government-issue contracts ABNC held simultaneously.

Private bank issues in Colombia were demonetized and withdrawn following the monetary centralization under the Banco de la República, established in 1923. Notes from Banco Colombiano that survived did so largely outside circulation, in collections or family hoards.
