廖内群岛（Kepulauan Riau，简称Kepri），印度尼西亚的岛群，位于苏门答腊以东，在马六甲海峡的东南入口，隔新加坡海峡同新加坡相望。由宾丹(Bintan，面积1075平方公里)等数百小岛组成，总面积约3835平方公里，多山地，地面崎岖，岛外多珊瑚礁。主要港市为丹戎摈榔(Tandjungpinang)，全群岛属印度尼西亚的廖内群岛省。

廖内群岛的居民以马来人为主，印度尼西亚、马来西亚和文莱都承认廖内群岛的马来语最标准，称为Bahasa Riau。许多语言学家认为廖内群岛是马来语的发源地。

Not to be confused with Riau Islands Province, a province (administrative) of Indonesia.

The Riau Archipelago is a geographic term (as opposed to administrative region) for the core group of islands within the Riau Islands Province in Indonesia, and located south of Singapore. Before the province of Riau Islands was formed, there was no ambiguity in term; however, in Indonesian both the archipelago and islands are referred to as simply "Kepulauan Riau". The province may have the word "Provinsi" preceding it.
