Malay Indonesians (Malay: orang Melayu Indonesia; Jawi ?) are ethnic Malays living throughout Indonesia as one of the indigenous peoples of the island nation. Indonesia has the second largest ethnic Malay population after Malaysia. Indonesian, the national language of Indonesia, is a standardized form of Riau-Johor Malay. There were a number of Malay kingdoms in Indonesia that covered the islands of Sumatra and Kalimantan, such as Srivijaya, Melayu Kingdom, Dharmasraya, Sultanate of Deli, Sultanate of Siak Sri Indrapura, Riau-Lingga Sultanate, Sultanate of Bulungan, Pontianak Sultanate, and the Sultanate of Sambas.
Sumatra is the homeland of the Malay languages, which today spans all corners of Insular Southeast Asia. The Indonesian language, which is the country's official language and lingua franca, was based on Riau-Lingga (or Johor-Riau) Malay. The Malay language has a long history, which has a literary record as far back as the 7th century AD. A famous early Malay inscription, the Kedukan Bukit Inscription, was discovered by the Dutchman M. Batenburg on 29 November 1920, at Kedukan Bukit, South Sumatra, on the banks of the River Tatang, a tributary of the River Musi. It is a small stone of 45 by 80 cm. It is written in Old Malay, a possible ancestor of today's Malay language and its variants. Most Malay languages and dialects spoken in Indonesia are mutually unintelligible with Standard Indonesian. The most widely spoken are Palembang Malay (3.2 million), Jambi Malay (1 million), Bengkulu Malay (1.6 million) and Banjarese (4 million) (although not considered to be a dialect of Malay by its speakers; its minor dialect is typically called Bukit Malay). Besides the proper Malay languages, there are several languages closely related to Malay such as Minangkabau, Kerinci, Kubu and others. These languages are closely related to Malay, but their speakers do not consider their languages to be Malay. There are many Malay-based creoles spoken in the country especially in eastern Indonesia due to contacts from the western part of Indonesia and during colonial rule where Malay replaced Dutch as a lingua franca. The most well-known Malay creoles in Indonesia are Ambonese Malay, Betawi, Manado Malay and Papuan Malay.
The Malay people in Indonesia fall into various sub-ethnicities with each having its own distinct linguistic variety, history, clothing, traditions, and a sense of common identity. According to 2000 census, Malay Indonesians include:
and various other smaller sub-groups.
Besides Malays proper, there are various ethnic groups throughout Sumatra, Java and Borneo which share close cultural, linguistic and historical ties with Malays but are classified separately by the Indonesian census, these are;
