The Weinviertel (German:[ˈvaɪ̯nˌfɪʁtl̩]ⓘ; English: 'Wine Quarter'; Czech: Vinná čtvrť; Slovak: Vínna štvrť) or Viertel unter dem Manhartsberg ("area below the Manhartsberg": Czech: oblast pod Manhartsbergem; Slovak: oblasť pod Manhartsbergem) is located in the northeast of Lower Austria.
Beside viticulture and agriculture, other industries contribute to the Weinviertel economy. Most notably, there are some oil fields in its eastern part, which are exploited by OMV and located in the "oil communities" of Neusiedl an der Zaya, Zistersdorf, Matzen, Auersthal and Prottes.
