Yoko Shimomura (下村 陽子, Shimomura Yōko, born October 19, 1967) is a Japanese video game composer and pianist. Shimomura has worked in the video game industry ever since graduating from the Osaka College of Music in 1988.

From 1993 until 2002, Shimomura worked for Square, where she composed for a further eight games.
