Battle Arena Toshinden (バトルアリーナ闘神伝, Batoru Arīna Tōshinden?) is a weapons-based fighting game for the PlayStation, Sega Saturn and PC. It was one of the first fighting games to boast polygonal characters in a 3D environment. It was an early killer game for the PlayStation, and Sony promoted it eagerly. However, they soon left the series, which was published by Playmates Interactive. By that time, fighting games like Tekken started emerging and Battle Arena Toshinden quickly lost popularity and was completely forgotten by the public after spawning Battle Arena Toshinden 2, 3, and 4.

Battle Arena Toshinden was the first 3D weapons fighter, and was succeeded in spirit by Soul Edge and other games of the genre.
