Fragaria iturupensis, the Iturup Strawberry, is a species of strawberry, endemic to Iturup in the Kuril Islands.

The mountains are covered with birch and Siberian Dwarf Pine scrub, herbaceous flowers (including Fragaria iturupensis, the Iturup strawberry) or bare rocks.

Fragaria iturupensis was initially reported as octoploid (with 8 sets of chromosomes, 56 in total), but subsequent testing found decaploids (with ten sets of chromosomes, a total of 70).

The Fragaria iturupensis seed was among 10,552 samples of seed recently sent to the seed vault by the Agricultural Research Service, an arm of the U.S. Department of Agriculture that promotes international food security.
