Singlish is an English-based creole language native to Singapore. It is the first language of many younger Singaporeans, especially those whose parents do not share a native language or dialect, and is the second language of nearly all the rest of the country's residents.

The vocabulary of Singlish consists of words originating from English, Malay (mainly Bahasa Melayu rather than Bahasa Indonesia), Hokkien, Cantonese, and to a lesser extent various other Indic and Sinitic languages, while Singlish syntax resembles southern varieties of Chinese. Also, elements of American and Australian slang have come through from imported television series. To date, other Asian languages like Japanese, Korean and other lesser known Chinese dialects such as Shanghainese have also been incorporated into Singlish.

Singlish is closely related to Manglish of neighbouring Malaysia
