Castlevania: Symphony of the Night, also known in Japan as Castlevania: Nocturne in the Moonlight (Japanese: 悪魔城ドラキュラＸ月下の夜想曲, Akumajō Dracula X: Gekka no Yasōkyoku, lit. "Dracula's Vampire Castle X: Nocturne in the Moonlight") is the metroidvania video game for PlayStation and Sega Saturn. Although the correct abbreviation would be CSN). It was the first Castlevania game released by Konami for the PlayStation and started the new style of Castlevania games known as "Metroidvanias", which were action-adventure games rather than traditional platformers.

The main protagonist is Alucard, son of Dracula, and ally of Trevor Belmont 347 years earlier (in Castlevania III: Dracula's Curse) and his Richter Belmont and Maria Renard. SotN is a direct sequel to Castlevania: Rondo of Blood
