The Javanese Malaysians are people of full or partial Javanese descent who were born in or immigrated to Malaysia. They form a significant part of Malaysia's population and Malaysian law considers most of them to be Malays. Malaysia is home to the largest Javanese population outside Indonesia. The Javanese are not the only Indonesian ethnic group that has assimilated into Malaysian society; there are also the Minangkabau people, Bugis people, Banjar people, Bawean people, and others.

The majority of Javanese Malaysians originate from Central Java; the first wave came during the Shailendra era from the sixth to ninth century, then during the Singhasari, Srivijaya, and Majapahit era from the twelfth to fourteenth century. Political marriages between kingdoms, such as the union between Sultan Mansur Shah of Malacca and Princess Raden Galuh Chandra Kirana of Majapahit, serve as evidence of long-standing inter-ethnic interactions. This story is recorded in the 16th-century classical Malay manuscript, Sulalatus Salatin.

There were also migrants from the Dutch East Indies looking for new opportunities in British Malaya. Although many of them arrived during the colonial era, there are also those who arrived during World War II to both Japanese-occupied British Malaya and Borneo as forced labour. In the present day, they live predominantly in the West Malaysian states of Johor, Perak and Selangor, with significant minorities found in East Malaysia, especially in the states of Sabah and Sarawak.

Most Malaysians of Javanese descent have assimilated into the local Malay culture and speak Malaysian as a native tongue and first language rather than the Javanese language of their ancestors. This occurred through usual assimilation, as well as intermarriages with other ethnic groups. This qualifies them as Malays under Malaysian law. The situation is identical with the Javanese in Singapore, where they are considered Malay. The presence of Javanese people in Malaysia has become part of history and contributed to the country's development. Many political figures hold important positions in the Malaysian government, including Dato' Seri Ahmad Zahid Hamidi, who served as Deputy Prime Minister of Malaysia (Deputy Prime Minister) since 29 July 2015, and Muhyiddin Yassin, the President of the Malaysian United Indigenous Party and former holder of several ministerial positions in Malaysia. Several Malaysian artists also have Javanese ancestry, such as Mohammad Azwan bin Mohammad Nor, widely known as Wak Doyok, an entrepreneur and fashion icon, and Herman Tino, a pioneer of dangdut music in Malaysia.

Nusantara is a term derived from two Sanskrit words: nusa (island) and antara (between). This is due to the geographical nature of the region, which consists of an archipelago of islands situated between the continents of Asia and Australia and located between the Indian Ocean and the Pacific Ocean. The History of Nusantara predates the formation of the modern nations now known as Indonesia, Malaysia, Singapore, Brunei Darussalam, and parts of the Philippines and Thailand. The peoples of the Nusantara region were historically united by ancient kingdoms such as Srivijaya, Majapahit, and other polities.

During the European colonial rule in Nusantara, many Javanese people were brought to the Malay Peninsula as laborers for oil palm and rubber plantations. Malaysia has a large Javanese-descended population, particularly in the State of Johor. Javanese people from Kulon Progo and Ponorogo migrated to the southern part of Johor from the 18th to the early 20th century. This Javanese diaspora mainly worked on plantations in Johor and Selangor. They preferred to live under British colonial rule, believing that the British treated indigenous laborers better than the Dutch Colonial Government.

Since the time of British colonial rule in Malaya, the capital of Selangor, Shah Alam, has been home to many Javanese migrants. In addition to the Javanese, there were also migrants from the Dutch East Indies, primarily from Sumatra Island, such as the Minangkabau people and the Acehnese people. These migrants established a settlement that is now known as Kampung Padang Jawa.

During its early establishment, Kampung Padang Jawa was a fertile agricultural area producing various fruits. At that time, its residents primarily worked as rubber tappers. Before the Klang River became polluted due to urban development, many villagers were fishermen, catching freshwater fish, giant river prawns, and belacan shrimp. The founder of Kampung Padang Jawa was a man named Wak Karian. According to local stories, Wak Karian was a courageous warrior and a respected figure within the community. He was of Javanese origin from Central Java. Wak Karian was the first person to clear land and establish Kampung Padang Jawa. His tomb can now be found in the Kampung Padang Jawa cemetery, located next to the Federal Highway in Selangor. The name Kampung Padang Jawa originates from the Javanese language, specifically from the word padhang, meaning "bright" or "illuminating an area." This refers to Wak Karian's efforts to open new land, which brought life and prosperity to the region. Over time, the settlement became widely known as Kampung Padang Jawa.
