Vapniarka (Ukrainian: Вапнярка), also known as Vapniarca, Vapnyarka, Wapnjarka or Wapniarka, is a rural settlement in Tulchyn Raion, Vinnytsia Oblast, Ukraine, known since 1870 as a railroad station.

From October 22, 1941, to March 1944, it was included in the region of Transnistria and became the site for a concentration camp for members of the Romanian Jewish community.

Today, Vapniarka serves as the final train destination for visitors traveling to villages in Tomashpilskyi and Yampilskyi Raion of Vinnytsia Oblast.

On this day, a new law entered into force which abolished this status, and Vapniarka became a rural settlement.

Some 200 died in a typhus epidemic; the others were taken out of the camp in two batches, guarded by soldiers of the Romanian Gendarmerie, and shot to death.
