Citing Norwegian-language newspaper Aftenposten, Xinhua said the 11-year-old boy was seriously ill for two weeks before being transferred from a hospital in Porsgrunn to the Riks Hospital in Oslo.
A doctor confirmed that the boy died of influenza A caused by the H1N1 virus.
The boy's family members were being monitored by medical workers.
