Haakon Sverresson (Norwegian: Håkon Sverresson, Old Norse: Hákon Sverrisson; c. 1183 – 1 January 1204) was King of Norway (being Haakon III) from 1202 to 1204. Biography Haakon was born as the second illegitimate son of the future King Sverre, then a Faroese adventurer. Historian P. A. Munch suggested that Haakon III's mother could have been Astrid Roesdatter, daughter of Bishop Roe in the Faroe Islands, but this has not been supported by later historians.

He also wrote a letter to Håkon advising him to settle the longstanding dispute with the church. When the news of Sverre's death reached Håkon and the Birkebeiner assembled in Nidaros, Håkon was first taken as chieftain by the Birkebeiner. The same spring he was taken as king at the thing in Nidaros. The same spring the Norwegian bishops, who had been in exile in Sweden and Denmark and had supported the Bagler, returned to Norway and made a settlement with Håkon. It seems likely that he gave in to most of their demands. Norway was released from the interdict it had been placed under during the reign of Sverre. Håkon is said to have been on friendly terms with the farmers and the common people, and the Bagler party soon lost much of its support.
