Kundur Island is an island within the Riau Archipelago, part of the Riau Islands Province of Indonesia. It lies at about 80 kilometres (50 miles) southwest of Singapore, 76 kilometres (47 mi) southwest of Batam, 32 kilometres (20 mi) south of Great Karimun Island, 172 kilometres (107 mi) northwest of Lingga Islands and 120 kilometres (75 mi) west of Tanjung Pinang. It has an area of about 304 square kilometres (117 sq mi), not including Buru District. According to the 2010 Census population, the population of Kundur Island was 67,090. As Kundur does not have an airport, all visitors arrive by ferry.

Most connections are with neighbouring islands, e.g. Tanjung Balai on Great Karimun Island, and mainland Sumatra. Direct ferry services to Singapore have been terminated because of decreasing profits, so travellers need to detour via Batam or Bintan.
