Jacobsen Valley (Bulgarian: долина Якобсен, ‘Dolina Jacobsen’ \do-li-'na 'ya-kob-sen\) is the shallow valley in Vinson Massif, Sentinel Range in Ellsworth Mountains, descending northwards from the summit of Antarctica Mount Vinson (4892 m). It is 3.5 km long and 1.2 km wide, and is bounded to the west by Branscomb Peak and Galicia Peak, and to the east by a minor ridge running between the east side of Mount Vinson to the south and Goodge Col to the north. Draining the valley is a glacier tributary to Branscomb Glacier, part of the classical route to the summit Mount Vinson.

The valley is named after the Norwegian woman pioneer of Antarctica Solveig Gunbjørg Jacobsen (1913–1996), the first native child of the Antarctic region born in Grytviken on 8 October 1913.
