Kaffeklubben Island or Coffee Club Island is a small island lying of the north eastern tip of Greenland, and is considered to be the most northerly point of land on earth.

Discovered by Robert Peary in 1900, the island is around 1km in length, and found at , 37km east of Cape Morris Jesup, Greenland. First visited by the Danish explorer Lauge Koch in 1921, he named it after the coffee club in Copenhagen's museum of mineralogy, and in 1969 a Canadian team calculated that its northernmost tip lies 750m further north than Cape Morris Jesup, thus claiming its record as the most northerly point on land.

Since then, several gravel banks have been found to the north, most notably Oodaaq, though there is debate as to whether Oodaaq Island or these other gravel banks should be considered for the record as they are rarely permanent, being regularly swallowed by the moving ice sheets, or becoming submerged in the ocean.
