Castlevania: Bloodlines is an action-adventure platform game developed and published by Konami for the Sega Genesis/Mega Drive gaming console. It was released in North America on March 17, 1994, in Japan one day later, and in Europe on March 20 of that same year under the title of Castlevania: The New Generation. It was the only Castlevania game released for that system.

The game was promoted as a completely original vampire-themed action series at the time of its release, known as Vampire Killer (バンパイアキラー Banpaia Kirā?), the game's Japanese title. A preview of the game that appeared in the back of the Akumajō Dracula X: Chi no Rondo Strategy Guide, referred to the game as a "Castlevania Gaiden".

The game is notable for being loosely tied to the Dracula novel written by Bram Stoker.
