Background: Hakka Chinese settlers played a foundational role in the early development of Kuala Lumpur. However, as in other historical settings, they were eventually outnumbered and geographically marginalized by Cantonese (Yue) speakers. Today, Hakka is one of several urban minority languages within Malaysia’s multilingual landscape. Material and Method: This study draws on data from an extended Hakka family in Kuala Lumpur and Selangor, linguistic observations from speakers across generations, and brief reflections on the role of clan associations (huìguǎn). Analysis: Hakka remains in use among older and middle-aged speakers but is undergoing rapid language change. Younger generations are abandoning it in favour of school-mediated standard language–especially Mandarin Chinese, now often used as the primary family language. Additionally, clan associations face declining youth engagement and are largely ineffective in preventing language shift, though they continue to support Chinese education. Parental attitudes generally favour Mandarin for its communicative and economic value. Discussion and Conclusions: In Kuala Lumpur, Hakka persists mainly as a familial spoken language among older speakers but is no longer being effectively transmitted to younger generations. Notably, it is not being replaced by the national language (Malay), but by a foreign standardized variety—Mandarin—promoted through education and media. This reflects a broader sociolinguistic transformation: the older multilingualism of spoken, non-standard varieties is being replaced by a new multilingualism based on three standardized languages–Chinese, Malay, and English.
