Margaretatop is a mountain in eastern Greenland. Administratively it is part of the Northeast Greenland National Park.

At the time of Lauge Koch's 1949–51 expeditions this summit was named after Margareta Hediger by American geologist John Haller, a Fellow of the Geological Society of America.

The peak is marked as "Margaretatopp" and "Margarita Spids" in some maps. Margaretasø is a small lake in neighboring Rendal at 73°25.5′N 26°39.0′W / 73.4250°N 26.6500°W / 73.4250; -26.6500 where the reflection of the mountain can be seen on its surface. This lake was named by John Haller after the same person.

Margaretatop is the highest point of Andrée Land.

It is a roughly 2,360 m (7,740 ft) high peak that rises in the southwestern part of Andrée Land, east of the Rendal valley and northeast of the shore of the Isfjord, a northern branch of Kaiser Franz Joseph Fjord. This mountain is marked as a 7,743-foot-high (2,360 m) peak in the Defense Mapping Agency Greenland Navigation charts.
