Madurese is a language of the Madurese people, native to the Madura Island and Eastern Java, Indonesia; it is also spoken by migrants to other parts of Indonesia, namely the eastern salient of Java, the Masalembu Islands and even some on Kalimantan. It was traditionally written in the Javanese script, but the Latin script and the Pegon script is now more commonly used. The number of speakers, though shrinking, is estimated to be 10-13 million, making it one of the most widely spoken languages in the country. Bawean Madurese, which is a dialect of Madurese, is also spoken by Baweanese descendants in Malaysia and Singapore.

Madurese, Madurans, Madurites or Madurace are one of the Javan ethnic groups native to the Indonesian island of Madura in Java Sea, off the northeastern coast of Java. They speak their own native Madurese language, shared common history, traditions, and cultural identity. Nationwide, the Madurese are the third largest ethnic group in Indonesia, and one of the well-known Indonesian national dishes of Satay also ultimately attributed as the national culinary heritage of Madura-origin invented by the Madurese.
