Citing an unidentified high-level UN source, Yonhap new agency said Ban would visit Pyongyang in his official capacity as secretary general later this week, though no precise dates were given.
The UN spokesman's office in New York declined to comment on the report.
The high-level UN source told Yonhap that Ban was almost certain to meet with North Korean leader Kim Jong-Un, who has yet to receive a single head of state since taking over power following the death of his father Kim Jong-Il in 2011.
Ban had been scheduled to visit North Korea in May this year, but Pyongyang withdrew its invitation at the last minute.
