Koichi Fukuda (born July 1, 1975) is a Japanese musician, best known as the lead guitarist, programmer, keyboardist, and co-founder of the American industrial metal band Static-X; he has been a member of the band three times, initially from 1994 to 2000, again from 2005 to 2010 and since 2018.

Drawing comparisons to Tool and Pink Floyd, they were successful locally and played several concerts in and around the Los Angeles area.

Koichi was with us back in the club days here in Los Angeles, played on our first record, Wisconsin Death Trip, and did the first two years of touring with the band.

In 2015, Fukuda was in the Australian rock band Bellusira, working out of Los Angeles.

In October 2018, it was announced that Fukuda – along with the other two surviving original members, bassist Tony Campos and drummer Ken Jay – would be involved in a reunion of Static-X, who were planning to release a new album and tour in 2019 in honor of the memory of their former bandmate Wayne Static.
