Barack Obama to visit Hiroshima on Asia trip
The visit will be part of an Asian trip from 21-28 May that will also take in Vietnam.
The Hiroshima bombing on 6 August 1945 killed 140,000 people. Along with a second bombing on Nagasaki - it is credited with ending World War Two.
Jimmy Carter has visited Hiroshima, but after the end of his presidency.
A statement from Mr Obama's press secretary read: "The President will make an historic visit to Hiroshima with Prime Minister [Shinzo] Abe to highlight his continued commitment to pursuing peace and security in a world without nuclear weapons."
The White House has ruled out any apology for the bombing.
The president's communications adviser, Ben Rhodes, said Mr Obama would "not revisit" the use of the atomic bomb in World War Two but would "offer a forward-looking vision focused on our shared future".
He said Mr Obama would "share his reflections on the significance of the site and the events that occurred there"'.
Mr Obama will also take part in the G7 summit in Japan's Ise-Shima peninsula and hold bilateral talks with Mr Abe.
Before that Mr Obama will meet Vietnam's leadership and deliver a speech in the capital, Hanoi, on US-Vietnam relations.
