WThe Blue Choir of Sam Ratulangi University is a students choir of Indonesia that consists of around 50 singers selected from full-time engineering students at Sam Ratulangi University.

Their repertoire, although widely varied in style, age and language, specifically emphasises works by Indonesian composers and music from Asia Pacific and other cultures. Performances by the choir regularly include commissioned works showcasing these uniquely North Sulawesi and Indonesian traditions.
