Chironomus okinawanus is a species of midge in the family Chironomidae.
The species was first described in 1987 by the Japanese entomologists Hideo Hasegawa & Manabu Sasa, from pupae and a male adult collected on Okinawa Island. It was later redescribed in 1995 as Chironomus tokarabeceus by Manabu Sasa & Hiroshi Suzuki, from a specimen collected from the Tokara Islands.
