Marija Gimbutas was a Lithuanian archaeologist and anthropologist known for her research into the Neolithic and Bronze Age cultures of "Old Europe" and for her Kurgan hypothesis, which located the Proto-Indo-European homeland in the Pontic Steppe.

Old Europe is a term coined by the Lithuanian archaeologist Marija Gimbutas to describe what she perceived as a relatively homogeneous pre-Indo-European Neolithic and Copper Age culture or civilisation in Southeast Europe, centred in the Lower Danube Valley. Old Europe is also referred to in some literature as the Danube civilisation.
