Hargreavesbreen (-72.1833°N 36°W) is a short, steep glacier flowing northwest between Mount Nils Larsen and Mount Widerøe in the Sør Rondane Mountains of Antarctica. It was mapped by Norwegian cartographers in 1957 from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named for R.B. Hargreaves, an aerial photographer on Operation Highjump photographic flights in this area and other coastal areas between 14°E and 164°E.
