The Geiyo Islands (芸予諸島, Geiyo Shotō) are a group of islands in the Seto Inland Sea, under the administration of Hiroshima Prefecture and Ehime Prefecture. Some of the largest islands in archipelago are connected by the Nishiseto Expressway bridge system connecting Honshu and Shikoku.

The Geiyo Archipelago is roughly defined as lying in the western part of Seto Inland Sea, from Hiuchi-nada [ja] to Aki-nada [ja]. A narrower definition of the archipelago only includes the islands between the former provinces of Iyo and Bizen. The islands of in Hiroshima Bay, most notably Etajima and Kurahashi-jima, are therefore excluded from the latter definition.

Due to the calm yet deep waters of the Seto Inland Sea, the Geiyo Islands are one of the main hubs of shipbuilding,^[1] fishing, and aquaculture in Japan.
