Altenhus Fortress (Norwegian: Altenhus festning; also Kongshus Fortress) was a fortification built on the island of Årøya in Finnmark county in Norway in 1610. The area is part of the present-day Alta Municipality.
Altenhus Fortress was intended to prevent Swedish incursions into the area, and secure the rich salmon fisheries for the Dano-Norwegian state. The structure only remained in military use for three years, before being abandoned and used as a prison until 1692, when the timber of the fortress' blockhouse was used in the construction of a church.
