King Christian IX Land (Danish: Kong Christian IX Land) is a coastal area of Southeastern Greenland in Sermersooq Municipality fronting the Denmark Strait and extending through the Arctic Circle from 65°N to 70°N.

[1] This area was named in September 1884 by Gustav Frederik Holm who claimed it for Denmark, naming it after the then-reigning Danish King Christian IX.

King Christian IX Land is bordered by King Frederick VI Coast on the south, King Christian X Land and the Scoresby Sound to the north, and the Greenland Ice Sheet to the west.

[2] The shore area of King Christian IX Land includes the Blosseville Coast to the east.

There are many fjords, the largest of which are Sermilik, Kangerlussuaq and Kangertittivatsiaq, as well as numerous coastal islands, including Ammassalik which is the site of the most populous town in Eastern Greenland, Tasiilaq.
