"The Cruel Angel's Thesis" (残酷な天使のテーゼ, Zankoku na Tenshi no Tēze), also known as "A Cruel Angel's Thesis", is a J-pop song performed by Japanese singer Yoko Takahashi. Toshiyuki Ōmori and Hidetoshi Satō composed the song, while Neko Oikawa wrote the lyrics. It was written for the opening theme of the anime television series Neon Genesis Evangelion, and was released as a double-A-sided single with "Fly Me to the Moon", the show's closing theme, on October 25, 1995. "The Cruel Angel's Thesis" was also included in the series' soundtrack releases and Takahashi's albums.

The song had a positive reception from music critics and audiences; it later became one of the most famous Japanese anisongs, songs specially created for anime series. Years after the show's first airing, "A Cruel Angel's Thesis" has remained a popular Japanese karaoke song, winning popularity polls and awards.
