德特冰川是南极洲的冰川，位于埃尔斯沃思地，处于埃尔斯沃思山脉的森蒂纳尔岭，长39公里、宽2至5公里，该冰川在1959年12月14至15日由美国海军发现。

The Dater Glacier is a steep valley glacier in Antarctica, 39 kilometres (24 mi) long and from 2 to 5 kilometres (1 to 3 mi) wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.
