横跨纬度北6度至南11度及经度东95度和141度，印尼也有‘千岛之国’的美称。她共有17，508座岛屿，其中只有6，000个岛屿可居住。放眼纵贯众多的岛屿，印尼也拥有其独特的民族特色，语言和宗教。较大的岛屿如Java，Sumatra，Borneo（与Malaysia和Brunei共有），New Guinea(与Papua New Guinea共有）及Sulawesi。首都Jakarta，位于Java岛上，是全国最大的城市。
印尼是世界第16大的国家，约1，919，440平方公里。Puncak Jaya山峰（高4，884米）于New Papua，是全国最高峰。Toba湖则是最大湖，面积约1，145平方公里。最宽的河则在Kalimantan，如Mahakam和Barito。
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania. Across its many islands, Indonesia consists of distinct ethnic, linguistic, and religious groups.
Indonesia lies between latitudes 11°S and 6°N, and longitudes 95°E and 141°E. It consists of 17,508 islands, about 6,000 of which are inhabited. These are scattered over both sides of the equator. The largest are Java, Sumatra, Borneo (shared with Brunei and Malaysia), New Guinea (shared with Papua New Guinea), and Sulawesi. The capital, Jakarta, is on Java and is the nation's largest city, followed by Surabaya, Bandung, Medan, and Semarang.
At 1,919,440 square kilometers (741,050 sq mi), Indonesia is the world's 16th-largest country in terms of land area. At 4,884 metres (16,024 ft), Puncak Jaya in Papua is Indonesia's highest peak, and Lake Toba in Sumatra its largest lake, with an area of 1,145 square kilometers. The country's largest rivers are in Kalimantan, and include the Mahakam and Barito.
Indonesia's location on the edges of the Pacific, Eurasian, and Australian tectonic plates makes it the site of numerous volcanoes and frequent earthquakes. Indonesia has at least 150 active volcanoes, including Krakatoa and Tambora, both famous for their devastating eruptions in the 19th century. The eruption of the Toba supervolcano, approximately 70,000 years ago, was one of the largest eruptions ever, and a global catastrophe. However, volcanic ash is a major contributor to the high agricultural fertility that has historically sustained the high population densities of Java and Bali.
Lying along the equator, Indonesia has a tropical climate, with two distinct monsoonal wet and dry seasons.
