Singaporenalli Raja Kulla (transl. Raja and Kulla in Singapore) is a 1978 Indian Kannada language action film directed by C. V. Rajendran starring Vishnuvardhan, Manjula, Dwarkish, Lokanath and Thoogudeepa Srinivas in pivotal roles.

Set and shot in Singapore, it was the first Kannada film to be shot outside India in a country which is not a neighbouring nation and the second Kannada movie to be shot outside India after Operation Diamond Racket (which was shot in Nepal and released four months before this movie). However, this movie is widely credited for having started the trend of shooting abroad. This was the first Kannada cinema to run over 200 days in the Belgavi region. The film was dubbed and released in Tamil as Sweet Singapore.
