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

It is noted to have relatively large berries for a wild species, similar in appearance to those of Fragaria virginiana.

[1][2] All strawberries have a base haploid count of 7 chromosomes.

Fragaria iturupensis was initially reported as octoploid (with 8 sets of chromosomes, 56 in total), but subsequent testing[3] found decaploids (with ten sets of chromosomes, a total of 70).

It is unclear whether the earlier report was an error, or whether two forms exist.
