Sostra Heights (Bulgarian: Состренски възвишения, ‘Sostrenski Vazvisheniya’ \'so-stren-ski v&-zvi-'she-ni-ya\) are the heights rising ro 2352 m at Mount Malone on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. They extend 22 km in northwest–southeast direction and 16.5 km in northeast–southwest direction. The heights are bounded by Embree Glacier to the south, Sabazios Glacier to the west, Newcomer Glacier to the north and Rutford Ice Stream to the east, and separated by Robinson Pass to the southwest from the side ridge that trends 9.15 km east-northeastwards from Mount Dalrymple on the main crest of Sentinel Range. Their interior is drained by Anchialus Glacier and Vit Ice Piedmont.

The heights are named after the ancient Roman fortress of Sostra in Northern Bulgaria.
