A featured topic is a collection of inter-related articles that are of a good quality (though not necessarily featured articles). A featured topic represents Wikipedia's best work by thoroughly covering all parts of that topic through several high-quality articles that share a similar structure and are well-linked with each other. To become featured, a topic must meet a set of criteria.
Featured topics are nominated and discussed at the Wikipedia:Featured and good topic candidates page, where they are either accepted or rejected. Additions to existing featured topics are also discussed there. Do not add an article directly to a featured topic without nominating it first.
There are currently 181 featured topics that encompass 1,551 unique articles. There are 55 articles concurrently in two featured topics, 11 articles in a featured topic and a good topic, 7 articles in two featured topics and a good topic, and 2 articles in a featured topic and two good topics. There are 48 topics in which every article is featured if possible.
