Castlevania is a 1999 action-adventure video game developed by Konami's Kobe branch for the Nintendo 64 video game console. An expanded version of the game, Castlevania: Legacy of Darkness, was released later in the same year.

Castlevania is the first 3D game in the Castlevania series. The player selects one of the game's protagonists to control: Carrie Fernandez, a young orphan gifted with magic powers, or Reinhardt Schneider, the whip-wielding heir to the Belmont clan (the series' recurring protagonists). Carrie and Reinhardt set out on a quest to stop Count Dracula's impending return to power after a century of dormancy. The characters travel to and explore Dracula's grand estate in their mission to defeat the count and his horde of undead minions.
