The meridian 45° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Greenland, the Atlantic Ocean, South America, the Southern Ocean, and Antarctica to the South Pole.
In Greenland the meridian defines the borders of Avannaata, Qeqertalik, and Qeqqata municipalities with the Sermersooq municipality and the Northeast Greenland National Park.
Greenland is divided into five municipalities and two unincorporated areas. The municipalities are Avannaata, Kujalleq, Qeqertalik, Qeqqata, and Sermersooq. Northeast Greenland National Park is a huge unincorporated area that is outside the municipalities and larger than any of them. Pituffik Space Base is a small unincorporated enclave surrounded by the Avannaata municipality and administered by the United States Space Force.
