Malaysian Chinese or Chinese Malaysians (Bahasa Malaysia: Kaum Cina Malaysia; Chinese: trad 馬來西亞華人, simp 马来西亚华人, pin Mǎláixīyà Huárén) are Malaysians of Chinese – particularly Han Chinese – descent. Most are the descendants of Chinese who arrived between the early and the mid-twentieth centuries. Malaysian Chinese constitute one group of Overseas Chinese and constitute the third largest Chinese community in the world, after those in Thailand and Indonesia. Within Malaysia, they are usually simply referred to as "Chinese" and represent the second largest ethnic group in Malaysia after the ethnic Malay majority. As of 2010, approximately 6,960,000 Malaysians – almost a quarter of the population – self-identify as "Chinese".
Malaysian Chinese are a socioeconomically well established middle-class ethnic group and make up a highly disproportionate percentage of Malaysia's professional and educated class, with a record of high educational achievement, a high representation in the Malaysian professional white-collar workforce, and one of the highest household incomes among minority demographic groups in Malaysia. Like in much of Southeast Asia, Malaysian Chinese are dominant in both the business and commerce sectors, controlling an estimated 70% of the Malaysian economy. They are also one of the biggest taxpayers, contributing almost 90% of the national income tax and 60% of Malaysia's national income.
