Skinnastaður () is a farm and rectory in northeastern Iceland, north of Vatnajökull National Park and 25 km from Dettifoss. It is a part of the Norðurþing municipality.
The church, Skinnastaðarkirkja, is known for its ornate wooden structure.
The farm is the subject of a legend about the location involving cursed carolers; the story goes that the original farmstead and church sank into the earth one Christmas Eve.
There is a seismic station located at the farm that is used to forecast volcanic eruptions, especially from Hekla.
