Laxárdalur is a valley located to the west of Tindastóll mountain in Skagafjörður County, Iceland.

It is 14 kilometers (8.7 miles) long[1] and heads toward the sea north of Tindastóll where it is called Sævarlandsvík.

The valley is located almost due south along Tindastóll, and to the west are low hills and ridges.

The river Laxá, which originates in Hryggjafjall mountain in Staðarfjöll, runs through the valley.

Hvammur was the church site and parsonage,[3] and thought to have been the homestead of Eilífur örn Atlason who, according to the Landnámabók, settled Laxárdalur.
