Owadowia is a genus of extinct thalassochelydian turtle from the Late Jurassic of Poland.

The type and only species is Owadowia borsukbialynickae, named by Szczygielski and colleagues in 2017 for a partial lower jaw, coracoid, ilium and femur from the early Tithonian Kcynia Formation.

[1] The limited material means that it is difficult to compare Owadowia to its relatives, and it may not be a unique taxon.

The genus lacks the features diagnostic to its parent clade Thalassochelydia, has similarities to Solnhofia and Portlandemys as well as being a Late Jurassic marine turtle like the remainder of the group.
