Roché Glacier (Bulgarian: ледник Роше, romanized: lednik Roshe, IPA: [ˈlɛdnik roˈʃɛ]) is the 5.8 km long and 2 km wide glacier draining the central part of Vinson Plateau in Sentinel Range, Ellsworth Mountains in Antarctica. Its head is bounded by Mount Vinson to the north, Corbet Peak and Clinch Peak to the east, Wahlstrom Peak to the southeast, and Hollister Peak to the south, with the glacier flowing westwards and descending steeply north of Silverstein Peak to join Branscomb Glacier.

The glacier is named after the British pioneer of Antarctica Anthony de la Roché who discovered the first land in the Antarctic region (Roché Island, present South Georgia) in 1675.
