The Notable Names Database (NNDB) is an online database of biographical details of over 40,000 people. NNDB describes itself as an "intelligence aggregator" of noteworthy persons highlighting their interpersonal connections. It is run by Soylent Communications, a sole proprietorship that hosted the now defunct


Each entry has an executive summary with an assessment of the person's notability. Vital statistics are listed, such as full name, pseudonyms, birth and death, location of any remains, religious beliefs, gender, race or ethnicity, sexual orientation, family members, relationships, and nationality. Contentious facts are footnoted. Some entries have a brief prose biography, or contain facts or citations. Entries may contain organization memberships, illnesses, phobias, addictions, drug use, criminal records, and other data. In the case of authors, actors, film directors, and architects, the entry lists the person's artistic works in chronological order.

Businesspeople and government officials have chronologies of their posts and positions, and board memberships. NNDB has articles on films with user-submitted reviews, discographies of selected music groups, and extensive bibliographies. Readers may suggest corrections on a form. A former feature was the "Level of Fame" assigned from "Niche" to "Icon".
As of September 2019, NNDB's “Dr. Sputnik” gossip page appeared to have its last entry in 2016. The owner of NNDB is listed as Soylent Communications, which redirects IP to the NNDB site.
