The Speak Mandarin Campaign is an initiative by the government of Singapore to encourage Singapore's Singaporean Chinese population to speak Mandarin, one of the four official languages of Singapore. The campaign is organised by the Promote Mandarin Council. From 1979 to 1981, the Speak Mandarin Campaign was targeted at Chinese Singaporeans, in particular, specific groups such as hawkers, public transport workers, white-collar workers and senior executives, to encourage them to speak Mandarin instead of non-Mandarin Chinese languages so that they could better communicate with each other, especially among various dialect groups. This objective has been largely achieved. However, research indicated that Mandarin was losing ground among English-educated Chinese Singaporeans who were starting to lose their Mandarin or Chinese language skills. The program coexists with other similarly run language advocacy campaigns, such as the Speak Good English Movement.
