The IGW Ilmarriven was an Andorian Empire warship, a Shran-class starship in service to the Andorian Imperial Guard in the late 24th century, under the command of Captain Kainon th'Liro.

In September 2385, the Ilmarriven apprehended the USS Aventine in the orbit of Andoria and became part of the standoff between Andorians, Starfleet and the Tholian Assembly while Doctor Julian Bashir evaded them to deliver a cure to the Andorians. (The Fall novel: A Ceremony of Losses)
