See-Saw was a Japanese pop duo (formerly a trio) originally from Tokyo, Japan. Its members included Chiaki Ishikawa (vocals) and Yuki Kajiura; former member Yukiko Nishioka (西岡 由紀子, Nishioka Yukiko) left the group in April 1994 to pursue a writing career. The group temporarily disbanded in 1995, but reunited in 2001.

The duo of Ishikawa and Kajiura performed opening and ending themes in several anime series, including .hack//SIGN and .hack//Liminality, two insert songs for Noir, the first ending theme to Mobile Suit Gundam SEED, and the final ending theme to Mobile Suit Gundam SEED Destiny.
