Carta marina et descriptio septentrionalium terrarum (Latin for Marine map and description of the Northern lands;[1] commonly abbreviated Carta marina) is the first map of the Nordic countries to give details and place names, created by Swedish ecclesiastic Olaus Magnus and initially published in 1539.

Only two earlier maps of the Nordic countries are known, those of Jacob Ziegler (Strasbourg, 1532) and Claudius Clavus (15th century).

The map covers the Nordic lands of "Svecia" (Svealand) and "Gothia" (Götaland) (both areas in Sweden), "Norvegia" (Norway), Dania (Denmark), Islandia (Iceland), Finlandia (Finland), Lituania (Lithuania) and Livonia (Estonia and Latvia).

[2] The 1.70 m wide by 1.25 m tall map was printed in black and white from nine 55x40 cm woodcut blocks sequenced from west to east and north to south and identified in the center with the letters A through I.

[5] Olaus complemented the map with Historia de gentibus septentrionalibus ("A description of the Northern peoples") printed in Rome, 1555.
