Grímsey is a small island in the country of Iceland, 40 kilometers (25 mi) off the north coast of the main island of Iceland and straddling the Arctic Circle, which shifts northward by about 14.5 meters per year. In January 2011 Grímsey had 86 inhabitants.
Until a vote in 2009 to amalgamate with Akureyri, it constituted the hreppur (municipality) of Grímseyjarhreppur, part of the county of Eyjafjarðarsýsla. The only settlement is Sandvík
