- You may also be looking for Wikipedia:Contentious topics, Wikipedia:Controversial articles or Category:Wikipedia controversial topics.
This is a list of Wikipedia articles deemed controversial because they are constantly re-edited in a circular manner, or are otherwise the focus of edit warring or article sanctions. This page is conceived as a location for articles that regularly become biased and need to be fixed, or articles that were once the subject of an NPOV dispute and are likely to suffer future disputes. The divisive nature of disputed subjects has triggered arguments, since opinions on a given issue differ. These subjects are responsible for a great deal of tension among Wikipedia editors, reflecting the debates of society as a whole. Perspectives on these subjects are affected by the time, place, and culture of the editor.
- Articles listed here may need more work than usual to approach a neutral point of view. For articles that are currently unbalanced, see NPOV dispute instead.
- Articles on this list should be checked from time to time to monitor developments in the presentation of the issues. Use the "related changes" link to quickly review changes to these articles.
- Discussions about those controversies should be limited to the relevant Talk pages. For more information, see Wikipedia:Controversial articles.

This is a list of Wikipedia articles deemed controversial because they are constantly re-edited in a circular manner, or are otherwise the focus of edit warring or article sanctions. This page is conceived as a location for articles that regularly become biased and need to be fixed, or articles that were once the subject of an NPOV dispute and are likely to suffer future disputes. The divisive nature of disputed subjects has triggered arguments, since opinions on a given issue differ. These subjects are responsible for a great deal of tension among Wikipedia editors, reflecting the debates of society as a whole. Perspectives on these subjects are affected by the time, place, and culture of the editor.
- Articles listed here may need more work than usual to approach a neutral point of view. For articles that are currently unbalanced, see NPOV dispute instead.
- Articles on this list should be checked from time to time to monitor developments in the presentation of the issues. Use the "related changes" link to quickly review changes to these articles.
