Infinite RYVIUS (無限のリヴァイアス, Mugen no Rivaiasu^?) is a 26 episode drama/sci-fi series produced by Sunrise. The series also refers to a manga.

The character and mecha designs in RYVIUS were created by Hisashi Hirai, who later went on to act as character designer for Gundam SEED.

The series is also noted for its music, a blend of western R&B/hip-hop music with J-pop vocals. This is evident in the opening song, "dis–", performed by bilingual Japanese-American singer Mika Arisaka. Most of the vocal songs were composed by M.I.D, and the thematic background instrumentals by Katsuhisa Hattori.

Set in the year AD 2225, mankind has spread from Earth to inhabit nearly all the planets or nearby moons in colonies and settlements. Space travel has grown and improved to the point of being commonplace. For the inhabitants of the solar system, an astronaut career isn't out of the question, and one of the schools set up to train future space voyagers is the Liebe Delta, a space station positioned somewhere in Earth's orbit. This growth is despite the mysterious phenomenon known as the Geduld, a sea of plasma that suddenly erupted from the sun along the Earth's orbital plane in AD 2137. Stretching from the sun to the edge of the solar system, this area of high temperatures and gravity pressures has never been explained.
