Kuria is one of the three islands that form the central district of the Gilbert group besides Abemama and Aranuka. It is made up of two islands with the mainland Kuria connected to the islet of Oneeke by a bridge. Kuria is well known for its great width (4.26 km) from the lagoon to the ocean side of the mainland when compared to the rest of the islands in the country. It lies 139 kilometers southeast from the capital Tarawa.

The main islet consisting of Marenaua, Bouatoa, Buariki, Tabontebike and Norauea villages. These villages are connected to Oneeke by a ten meter bridge replacing the old causeway that ran across the former reef passage between the two islets.

The two islets are relatively wide as compared to most islands in the Gilbert group. The widest portion measures 4.26 km from lagoon to the ocean side and the length from north south is 8.94 km. There are two natural two brackish-water ponds at east-southern tip of the main islet.

The total land area of Kuria is of 15.48 sq.km, which is close to the average size for an island of Kiribati, but the population is 1099 people, making Kuria one of the least populated islands in Kiribati.

A gravel road stretches across and around Kuria main islet, and another around Oneeke. These provide access to most inner parts of both islets.
