Nansenflua is an undersea rock in the northern part of Rekvedbukta off the southeastern coast of Jan Mayen in the Arctic Ocean. The shoal is named after the ship HNoMS Fridtjof Nansen, which sank after striking the previously uncharted rock in November 1940.{{Cite journal |last=Richter |first=Søren |title=Jan Mayen i krigsårene: Minner fra det første stykke norsk land vi besatte og holdt under hele krigen |language=no |journal=Norwegian Journal of Geography|year=1946 |volume=11 |issue=2 |page=15 |doi=10.1080/00291954608551617}}{{cite book |title=Arctic Pilot: Sailing directions Svalbard–Jan Mayen |year=1988 | volume =7 |publisher=The Norwegian Hydrographic Service and The Norwegian Polar Institute |location=Stavanger |isbn=978-82-90653-06-9 |pages=405–406 }}{{cite book |last=Selinger |first=Franz |title=Von "Nanok" bis "Eismitte": meteorologische Unternehmungen in der Arktis 1940–1945 |series=Schriften des Deutschen Schiffahrtsmuseums |volume=53 |location=Hamburg |publisher=Convent |year=2001 |url=https://books.google.com/books?id=1nocAQAAMAAJ&q=Nansenflua |page=26 |language=de|isbn=9783934613126 }} Nansenflua is the only obstruction in Rekvedbukta. The name Nansenflua was introduced in charts published by the Norwegian Polar Institute in 1955, and is included as a recognized name in Anders K. Orvin's 1960 paper The place-names of Jan Mayen. It follows a convention based on two then in force Orders in Council, dated 28 April 1933 and 31 May 1957, of using the Nynorsk grammatical form. The suffix "-a" in the feminine definite form was chosen, as no local dialect existed on Jan Mayen. The last part of the name, "flu(a)", means "rock awash", or "sunken rock". The geographical location is given by Orvin as {{Coord|70|57|N|08|28|W|display=inline}}, with an exactitude of 1'.{{cite book|title=The place-names of Jan Mayen |first=Anders K |last=Orvin |author-link=Anders K. Orvin |publisher=Norsk Polarinstitutt |year=1960 |series=Skrifter |volume=120 }} The rock, located two meters under the surface, has a small top area and vertical sides of about twenty meters. It is located about one nautical mile from Eggøykalven and 1.7 nautical miles west-southwest of the peninsula Eggøya.{{cite web |url=http://placenames.npolar.no/stadnamn/Nansenflua |title=Nansenflua (Jan Mayen) |publisher=Norwegian Polar Institute |access-date=4 August 2013}}{{cite book |last1=Liversidge |first1=Douglas |last2=Schøning |first2=Einar Th.

The rock is part of the remains of a crater.
