Keiko Terada (寺田恵子, Terada Keiko, born 27 July 1963) is a Japanese rock singer. She was co-founder and lead singer of the successful Japanese female hard rock and heavy metal band Show-Ya from 1982 to 1991, before going solo. On her solo albums she expanded from hard rock and heavy metal to blues, pop and soul.

Terada's trademark for many years was a fake rose tattoo she wore above her right breast. She was inspired by Bette Midler's film The Rose, in which Midler played a Janis Joplin-like character.

She maintained over the years a relevant presence in both Japanese TV and Radio, both alone and as member of other bands. She is now member of the reformed Show-Ya and of the special group Nishidera Minoru.
