The Three-year Expedition (Danish: Treårsekspeditionen) was an exploratory expedition to East Greenland that lasted from 1931 to 1934 financed by the Carlsberg Foundation and the Danish state. The expedition included aerial surveys. ^[1]

Many geographic features in East Greenland were mapped and named during the expedition. Eskimonaes station was used as a wintering base by the Three-year Expedition to East Greenland.^[2]

The expedition was led by Lauge Koch. The other participants were Danish and Swedish geographers, geologists, archaeologists, zoologists and botanists: Paul Gelting, Gunnar Seidenfaden, Thorvald Sørensen, Steen Hasselbach, Helge G. Backlund, Gunnar Thorson, Gunnar Säve-Söderbergh, Helge Larsen, Thyge Johansen, L. Bruhn, H. Heinrich Nielsen and N. V. Petersen. The expedition vessels were Godthaab and Gustav Holm.^[3] The engagement of the Danish state had political connotations, because of the ongoing dispute between Denmark and Norway over East Greenland.
