Theregions ofIceland are eight areas of Iceland that roughly follow the arrangement ofparliamentary constituencies as they were between 1959 and 2003. These regions are not incorporatedpolities but rather recognized groupings of municipalities. Iceland only has two levels of administration, the national government and 62municipalities. The municipalities have organized themselves into eight regional associations[1] and those boundaries are also recognized byStatistics Iceland to report statistics.[2] Since 2014,police and commissioner (sýslumaður) districts have followed the eight region model with the exception thatVestmannaeyjar forms a special district and not part of the Southern Region. The divisions of Iceland for the purposes of health care and district courts diverge more from the commonly used eight region model.
Thepostal code system also roughly corresponds with the regions with the first digit of the three digit codes usually being the same as on the map below.

Until 1957, the parliamentary constituencies used in Iceland had been based on itscounties andmarket towns. The reform of constituency borders in 1957 would group these counties and towns together into eight larger areas that form the basis for the modern regional division of Iceland. The differences between the 1957 boundaries and the modern ones are:
