David Sugden (b. 5 March 1941) is a glaciologist and glacial geomorphologist. His research focuses in particular on glacial and polar landforms, Antarctic ice sheet stability, and the dynamics of the Patagonian ice cap under a changing climate.

He studied at the University of Oxford, and graduated with a BA in 1962. He then took up an offer for a three-year research studentship funded by the Department of Scientific and Industrial Research, and spent these three years working on the glaciation of the Cairngorms until he graduated with a DPhil in 1965. Immediately after, he spent one year in the South Shetland Islands as a scientific officer for the British Antarctic Survey, before becoming a Lecturer and then a Reader at the University of Aberdeen, where he taught polar geography. In 1968, he organised with his wife Britta the Aberdeen University Greenland Expedition, which involved a mixed party of students. Sugden stayed in Aberdeen for 20 years, until he moved to Edinburgh as Professor in January 1967. He was Head of Geography twice (1987-92 and 1997-2000), and transformed the Geography department to one of the best in the UK. In Aberdeen and in Edinburgh, David Sugden taught courses on glaciers and glaciology (his specialism) and on geomorphology; several of which included field courses and fieldtrips in various locations, such as the Dee Estuary, Lochnagar and the surrounding area, the Balmoral Estate, Snowdonia, Greenland, and Iceland.

In 2003, the University of Edinburgh amalgamated departments into larger schools. David Sugden was persuaded by Grahame Bulfield, former Head of the Roslin Institute, to become the Head of GeoSciences. They brought together Geophysics, Geology, Geography, Meteorology, Ecology, and Environmental Chemistry to form the largest such grouping in the UK, and the only one involving both natural and social sciences. Sugden was Head of GeoSciences until 2006, and then became Acting Director at SAGES (Scottish Alliance for Geoscience, Environment and Society) in 2006-2007. He is now Emeritus Professor at the University of Edinburgh.
