Hegra Fortress (Norwegian: Hegra festning) is a small mountain fortress in the village of Hegra in Stjørdal Municipality in Trøndelag county, Norway. Originally known as Ingstadkleiven Fort (also Ingstadkleiva Fort), it was built between 1908–1910 as a border fort as a defence against the perceived threat of a Swedish invasion.
