Singaporenalli Raja Kulla (transl. Raja and Kulla in Singapore) is a 1978 Indian Kannada-language action film directed by C. V. Rajendran and produced by Dwarakish. The film stars Vishnuvardhan and Dwarkish, alongside Manjula, Felina, Lokanath, Uma Shivakumar, Shakti Prasad and Thoogudeepa Srinivas. The music was composed by Rajan–Nagendra, while cinematography and editing were handled by D. V. Rajaram and Yadav Victor.

Set and shot in Singapore, Singaporenalli Raja Kulla was the first Kannada film to be shot outside India in a country, which is not a neighbouring nation. It is also the second Kannada film to be shot outside India after Operation Diamond Racket (which was shot in Nepal and released four months before this film). However, it was widely credited for having started the trend of shooting abroad.

Singaporenalli Raja Kulla was the first Kannada film to run over 200 days in the Belgavi region. The film was dubbed and released in Tamil as Sweet Singapore.
