Inge Baardson (1185 – 23 April 1217) is king of Norway from 1204 to 1217.

His reign is within the later stages of the period known in Norwegian history as the age of civil wars.

Inge is the king of the birkebeiner faction.

The conclusion of the settlement of Kvitsøy with the bagler faction in 1208 leads to peace for the last nine years of Inge’s reigns, at the price of Inge and the birkebeiner recognizing bagler rule over Viken (the Oslofjord-area).
