What is the process for getting a Wikipedia page undeleted?

There are two paths back to a deleted Wikipedia article. The first is Deletion Review (WP:DRV), which is appropriate when the original deletion misapplied policy – for example, a notability assessment that overlooked existing coverage or a deletion discussion that did not follow proper procedure. DRV is a formal process: the requesting editor presents the specific procedural or policy error, and the community reviews. The second path is recreation, which requires materially new notability evidence: substantial mainstream coverage published after the deletion that establishes the subject’s notability through independent reliable sources. Recreating an article without new evidence typically results in speedy deletion under WP:G4 (recreation of deleted material) and can lead to article protection against recreation. The careful path is to build the source environment first and then propose a new article through Articles for Creation review.
