Felix König (born c.1880) was an Austrian scientist, alpinist and Antarctic explorer. He was a member of Wilhelm Filchner's Second German Antarctic Expedition, 1911–13, which failed in its attempt to determine the nature of the link, if any, between the Weddell Sea and the Ross Sea, and thereby resolve the question as to whether the continent was a single landmass or a group of several elements. In the course of the expedition König, along with Filchner, was part of the group, that disproved the existence of the land known as New South Greenland, or "Morrell's Land", supposedly discovered in 1823 by the American sealer captain, Benjamin Morrell.
