Svartárdalur is a valley deeper into the interior of Skagafjörður, Iceland.
It was previously a part of Lýtingsstaðahreppur,[1] but now belongs to Skagafjörður County.
It is a rather short valley and the Svartá river runs through it.
The homestead Írafell is in the valley.
[3] There is another Svartárdalur and another Svartá on the Húnavatnssýsla side of the mountain and they are occasionally confused because they are so close to each other.
