Oleshky Sands National Nature Park (Ukrainian: Олешківські піски національний природний парк) is a national park of Ukraine, located south of the lower Dnieper River about 25 km east of the regional city of Kherson, and 70 km northwest of the Crimean Peninsula.

As of 2019, visits by unaccompanied members of the public were strictly prohibited, with warnings that the area was next to a military training ground.

[3][4] Oleshky Sands is located in the Pontic–Caspian steppe ecoregion, a region that covers an expanse of grasslands stretching from the northern shores of the Black Sea to western Kazakhstan.

[5] The landscape is quite varied, with sandy-steppe, semi-arid steppe, meadows, reed beds, and forest stands.

The dunes of the Radensk sector are interspersed with patches of shrubs, lakes and birch groves (12% of the area).
