It will take on the name of its Danish parent company as part of a restructuring of its operations across Northern Ireland and the Republic.
National Irish Bank will also be rebranded as Danske.
Eivind Kolding from the company said: "It is not without sadness that we say goodbye to the Northern Bank brand name and replace it with Danske Bank.
"Northern Bank is a long-established and well-respected brand, but with our new organisational set-up, our overall ambition is to create an even better bank for our customers that is internationally recognised for its strength and expertise."
Meanwhile the bank announced it is writing off over £75m, leaving it with a loss of £55m for the first quarter of 2012 over bad debts.
Operating profits before impairments and provisions were up to £18m, representing a 51% increase - but that was hit by impairment charges of £72.5m.
Chief Executive Officer Gerry Mallon said the local economy "remains fragile" and this reflects the continued level of impairment charges.
He said: "I am very pleased with the strong underlying performance of our business, with profit up 51% and income and costs moving strongly in the right direction.
"However, we are not immune to the environment in which we operate. National and international market conditions remain challenging and have led to a continued high level of impairment charges.
"There is no doubt that 2012 will be a tough year for Northern Ireland, with continued low economic growth, low interest rates and a sluggish property market leading to elevated impairment charges.
"Our clear direction, competitive products and services and appetite for growth we are also well equipped to strengthen our market position further."
