Northeastern (Icelandic: Norðurlandi eystra) was one of the multi-member constituencies of the Althing, the national legislature of Iceland.

The constituency was established in 1959 following the nationwide extension of proportional representation for elections to the Althing.

It was abolished in 2003 following the re-organisation of constituencies across Iceland when it was merged with the Eastern constituency to form the Northeast constituency.

(Excludes compensatory seats.)
