Najica Blitz Tactics (Japanese: ナジカ電撃作戦, Hepburn: Najika Dengeki Sakusen) is an anime television series by Studio Fantasia and Amber Film Works. It aired in Japan from October to December 2001. The series is similar to that of Agent Aika, both being directed by Katsuhiko Nishijima and animated by Studio Fantasia, with much of the same content.

Though Najica was later adapted into a manga by Takuya Tashiro (田代 琢也, Tashiro Takuya), the majority of the difference in content were in the context of the missions and especially the ending.
