RV Oceania, or SY Oceania, is a tall ship, owned by the Polish Academy of Sciences, and used as a research vessel.

She was built in 1985 in the Gdańsk Shipyard in Poland, after the design of Zygmunt Choreń.

The hull was based on plans of earlier tall ships: ORP Iskra II and Pogoria, but its rigging was different.

Oceania was originally a full-rigged ship, with three masts (each 32 metres high).

The ship is equipped with laboratories able to provide hydrographic, optic, acoustic, chemical, biological and particulate experiments and observations.
