A good article (GA) is a Wikipedia article that meets a core set of editorial standards, the good article criteria, passing through the good article nomination process successfully. They are well-written, contain factually accurate and verifiable information, are broad in coverage, neutral in point of view, stable, and illustrated, where possible, by relevant images with suitable copyright licenses. Good articles do not have to be as comprehensive as featured articles (FA), but they should not omit any major facets: a comparison of the criteria for good and featured articles describes further differences.
Out of the 7,153,499 articles on Wikipedia, 43,607 are categorized as good articles (about 0.61% or 1 in 164), which are listed below. An additional 6,883 are listed as featured articles (about 1 in 1,040) and 4,761 as featured lists (about 1 in 1,510). Because articles are only included in one category, a good article that has been promoted to featured status is removed from the good articles category. Adding good and featured articles and lists together gives a total of 55,251 articles (about 0.77% or 1 in 130). A small green icon of a plus sign inside a circle () appears in the top-right corner of the article indicating that the article is good.
Any significant contributor may nominate an article if they believe it meets the good article criteria. Any impartial editor may review the article from the queue of good article nominations. If it meets the criteria, it is added to the list of good articles below. There are instructions for nominators and reviewers. Similarly, anyone who believes that an article no longer meets the good article criteria may propose to delist it by following the instructions for reassessment.
