Janina Celina Oszast (2 February 1908 – 7 October 1986) was a Polish biologist, palaeobotanist and educator. She was also a member of the resistance movement Union of Armed Struggle's Home Army during World War II. In 1977, Oszast was among the first Polish palaeobotanists attempting biogeographic synthesis of Miocene land sediments.

In the aftermath of World War II, Oszast was imprisoned twice. She was released early on both occasions as part of an amnesty. She was arrested and imprisoned again in late 1952, but she was released on parole in December 1954. She subsequently served in the Polish Academy of Sciences from 1956 until her retirement in 1978.
