Strengereid is a village in the municipality of Arendal in Agder county, Norway. It is located along the Norwegian County Road 410, about 3 kilometres (1.9 mi) northeast of the village of Eydehavn and just west of the island of Flostaøya. The village of Sagene lies about 2 kilometres (1.2 mi) to the northwest.

Originally, Strengereid was part of the municipality of Tvedestrand, but on 1 January 1962, the Strengereid area was merged with the neighboring municipalities of Flosta (west), Stokken (south), and Austre Moland (northwest) to form the new municipality of Moland. At that time Strengereid had 375 inhabitants. Then, on 1 January 1992, Moland was incorporated into Arendal.
