The Weinviertel (Austrian German:[ˈvaɪnˌfɪrtl̩]ⓘ; Czech: Vinná čtvrť; Slovak: Vínna štvrť; English: "Wine Quarter") or Viertel unter dem Manhartsberg (Czech: oblast pod Manhartsbergem; Slovak: oblasť pod Manhartsbergem; "Area below the Manhartsberg") 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.
