Malaysian Chinese or Chinese Malaysians are Malaysian citizens of Chinese ethnicity. They form the second-largest ethnic group in Malaysia, after the Malay majority, and as of 2020, constituted 23.2% of the country's citizens. In addition, Malaysian Chinese make up the second-largest community of overseas Chinese globally, after Thai Chinese. Within Malaysia, the ethnic Chinese community maintains a significant and substantial presence in the country's economy.
Most Malaysian Chinese are descendants of Southern Chinese immigrants who arrived in Malaysia between the early 19th and the mid-20th centuries before the country attained independence from British colonial rule. The majority originate from the provinces of Fujian and Lingnan (including the three modern provinces of Guangdong, Hainan and Guangxi). They belong to diverse linguistic subgroups speaking Chinese such as the Hokkien and Fuzhou from Fujian, the Teochew, Cantonese, Hakka from Guangdong, the Hainanese from Hainan and Kwongsai from Guangxi. Most Malaysian Chinese have maintained their Han Chinese heritage, identity, culture and language.
