Nobuo Uematsu (植松伸夫 Uematsu Nobuo?, born March 21, 1959) is a Japanese video game composer and musician, best known for scoring the majority of titles in the Final Fantasy series. He is regarded as one of the most famous and respected composers in the video game community. Uematsu is a self-taught musician; he began to play the piano at the age of eleven or twelve, with Elton John as his biggest influence.

Uematsu joined Square (later Square Enix) in 1985, where he met Final Fantasy creator Hironobu Sakaguchi. They have worked together on numerous titles, most notably the games in the Final Fantasy series. After nearly 20 years in the company, he left Square Enix in 2004 and founded his own company called Smile Please, as well as the music production company Dog Ear Records. He has since composed music as a freelancer for video games primarily developed by Square Enix and Sakaguchi's development studio Mistwalker.

A handful of soundtracks and arranged albums of Uematsu's game scores have been released. Pieces from his video game works have been performed in concerts worldwide, and numerous Final Fantasy concerts have also been held. He has worked with Grammy Award-winning conductor Arnie Roth on several of these concerts. In 2002, he formed a rock band with colleagues Kenichiro Fukui and Tsuyoshi Sekito called The Black Mages, in which Uematsu plays the keyboard. The band plays arranged rock versions of Uematsu's Final Fantasy compositions.
