Landsbanki (literally "national bank"), also commonly known as Landsbankinn (literally "the national bank") which is now the name of the current rebuilt bank (here called "New Landsbanki"), was one of the largest Icelandic commercial banks that failed as part of the 2008–2011 Icelandic financial crisis when its subsidiary sparked the Icesave dispute. On October 7, 2008, the Icelandic Financial Supervisory Authority took control of Landsbanki and created a new bank for all the domestic operations called Nýi Landsbanki (new Landsbanki) so that the domestic bank could continue to operate, the new bank continued to operate under the Landsbanki name in Iceland.

From 1927 to 1961 the bank had acted as the central bank, until it was replaced by the Central Bank of Iceland, although this interest was primarily directed towards note issuance rather than monetary policy. The bank had been state owned and was privatized in stages between 1998 and 2003.
