The name of the village originated from the living folk name of the inhabitants of Orešan, from the useful walnut tree. The motivation was certainly the fact that the original inhabitants grew a walnut tree in their gardens, orchards, vineyards and that it thrived there. Later, the orientational adjective Dolné was added to it (due to the neighboring Horné Orešany).
