The Extremaduran Wikipedia (Extremaduran: Güiquipedia n'estremeñu) or Güiquipedia (formerly Güiquipeya[1]) is the Extremaduran-language edition of Wikipedia, a free, online encyclopedia.

[2] It has 3,892 articles and is ranked 228th in the Wikipedia list according to the number of articles.

[3] Different media have criticized the Extremaduran version of Wikipedia.

It is questioned that the Extremaduran is not really a separate language, but instead a dialect of Asturian and Castilian, and that it does not have defined spelling rules,[4] although the OSCEC (Monitoring and Coordination Body of Extremaduran and its Culture) has worked on the standardization of Extremaduran through dictionaries and normative grammar materials.

[5] The fact that the page only has three main contributors, the same who initiated the project, has also been the subject of controversy.
