Thomas Romain (French pronunciation: [tɔmɑ ʁɔmɛ̃]; born 1977 or 1978) is a French animator who is responsible for creating Code Lyoko alongside Tania Palumbo. He is also responsible for designing and co-directing the Franco-Japanese animated series Ōban Star-Racers, which would be the start of his career in Japan.

In early 2017 Romain attracted mainstream media attention when he began tweeting illustrations he had drawn based on his children's sketches.
