Leizhou Min in the context of "Min Nan"

Min is a broad group of Sinitic languages with about 75 million native speakers. These languages are spoken in China in a region centered on modern Fujian Province, stretching from Southern Zhejiang to Eastern Guangdong, as well as on Hainan Island and the neighbouring Leizhou Peninsula. Min varieties are also spoken in Taiwan, and by a large international diaspora, particularly in Southeast Asia. The name Min is shared with the Min River in Fujian, and is also the abbreviated name of Fujian Province. Min languages are not mutually intelligible with one another nor with other varieties of Chinese.

The most widely spoken variety of Min outside of China is Hokkien, a variety of Southern Min which has its origin in Southern Fujian. Amoy Hokkien is the prestige dialect of Hokkien in Fujian, while a majority of Taiwanese people speak a dialect called Taiwanese Hokkien or simply Taiwanese. The majority of Chinese Singaporeans, Chinese Malaysians, Chinese Filipinos, Chinese Indonesians, Chinese Thais, and Chinese Cambodians are of Southern Min-speaking background (particularly Hokkien and Teochew), although some of these communities are shifting to national or regional languages. Communities speaking Eastern Min, Pu-Xian Min, Haklau Min, Leizhou Min, and Hainanese can also be found in parts of the Chinese diaspora, such as in Malaysia, Singapore, and Indonesia.

Southern Min (simplified Chinese: 闽南语; traditional Chinese: 閩南語; pinyin: Mǐnnányǔ; Pe̍h-ōe-jī: Bân-lâm-gí/gú; lit. 'Southern Min language'), Minnan (Mandarin pronunciation: [mìn.nǎn]) or Banlam (Min Nan Chinese pronunciation: [bàn.lǎm]), is a group of linguistically similar and historically related Chinese languages that form a branch of Min Chinese spoken in Fujian (especially the Minnan region), most of Taiwan (many citizens are descendants of settlers from Fujian), Eastern Guangdong, Hainan, and Southern Zhejiang. Southern Min dialects are also spoken by descendants of emigrants from these areas in diaspora, most notably in Southeast Asia, such as Singapore, Malaysia, the Philippines, Indonesia, Brunei, Southern Thailand, Myanmar, Cambodia, Southern and Central Vietnam, as well as major cities in the United States, including in San Francisco, in Los Angeles and in New York City. Minnan is the most widely-spoken branch of Min, with approximately 34 million native speakers as of 2025.

The most widely spoken Southern Min language is Hokkien, which includes Taiwanese.Other varieties of Southern Min have significant differences from Hokkien, some having limited mutual intelligibility with it, others almost none. Teochew, Longyan, and Zhenan are said to have general mutual intelligibility with Hokkien, sharing similar phonology and vocabulary to a large extent. On the other hand, variants such as Datian, Zhongshan, and Qiong-Lei have historical linguistic roots with Hokkien, but are significantly divergent from it in terms of phonology and vocabulary, and thus have almost no mutual intelligibility with Hokkien. Linguists tend to classify them as separate languages.

Hainanese or Hainamese (Hainan Romanised: Hái-nâm-oe, Hainanese Pinyin: Hhai3 nam2 ue1, simplified Chinese: 海南话; traditional Chinese: 海南話; pinyin: Hǎinánhuà), also known as Kengbun/Kengvun (simplified Chinese: 琼文话; traditional Chinese: 瓊文話), Keng language (琼语; 瓊語) or Hainam Min (海南闽语; 海南閩語) is a language of Min Chinese spoken in the island of Hainan and regional overseas Chinese communities in Thailand especially.

In the classification by Yuan Jiahua, it was added to the Southern Min group by Him despite being mutually unintelligible with Southern Min varieties such as Hokkien and Teochew. In the classification of Li Rong, used by the Language Atlas of China, it was treated as a separate Min subgroup. Hou Jingyi combined it with Leizhou Min, spoken on the Leizhou Peninsula, in a Qiong–Lei group. "Hainanese" is also used for the language of the Li people living in Hainan, but generally refers to Min varieties spoken in Hainan.
