Ryohgo Narita (Japanese: 成田 良悟, Hepburn: Narita Ryōgo, born May 30, 1980) is a Japanese light novelist and manga writer. He won the Gold Prize in the 9th Dengeki Novel Prize for Baccano!, which was made into an anime television series in 2007. His series Durarara!! was also made into two anime television series, one airing January 2010 and the second in January 2015.

Narita's works all feature a single thematic style, involving an ensemble cast of characters (each with their own viewpoint chapters) finding their lives intersecting with each other in various ways due to a supernatural entity, and more often than not getting into conflict with each other. Additionally, the first four light novel titles below take place within a shared universe known by fans as the "Naritaverse", featuring fantastical elements within an otherwise normal society.
