The New Batman Adventures (often shortened as TNBA) is an American animated superhero television series based on the DC Comics superhero Batman, which aired on Kids' WB from September 13, 1997 to January 16, 1999. Produced by Warner Bros. Television Animation, it is a continuation of Batman: The Animated Series (1992–1995) and the third series in the DC Animated Universe. It was followed by Batman Beyond (1999–2001). The series was revamped from BTAS, replacing its art style with streamlined designs to allow for more consistent animation and maintain similarity with the simultaneously running Superman: The Animated Series (1996–2000), with episodes airing on Kids' WB under the title The New Batman/Superman Adventures.

Stories in this series tend to give more focus to Batman's supporting characters, which include fellow crimefighters Robin, Nightwing and Batgirl, among others. The show also features guest characters such as Supergirl, Etrigan the Demon and The Creeper, characters who would later appear with Batman in Justice League and Justice League Unlimited. The 2001 video game Batman: Vengeance and its 2003 follow-up Batman: Rise of Sin Tzu are based on this series.
