An anime series of the same name was produced by Gonzo. Directed by Umanosuke Iida, the series was based on the manga, but used a screenplay by Chiaki Konaka and is significantly different from the manga in terms of plot, though it uses some of the same characters and similar character designs.

An original video animation (OVA) entitled Hellsing Ultimate is being produced by Satelight and Geneon. It follows the manga storyline more closely than the anime. The first episode was released in Japan on January 22, 2006, and as of July 2009, six episodes have been released with the 7th expected out by the end of 2009. The 6th OVA is also the first volume of the series to be available on both DVD and Blu-ray. So far only four episodes have been released in North America.
