Jona Eliëser Joseph Oberski (20 March 1938) is a Dutch Holocaust survivor.

A year before his birth, his Jewish parents fled Nazi Germany, settling in Amsterdam. However, after WWII broke out, the Netherlands were soon occupied, and the Oberskis were interned in the Bergen-Belsen concentration camp: Jona survived, unlike both his parents.

In 1962, he started to work for the National Institute for Subatomic Physics in Amsterdam. Oberski is married, having three children. He wrote several memoirs about his experience in the Holocaust, including 'Childhood' (1978), dedicated to his foster parents.
