Ralf Poelman (born 28th of December, 1980) is a Dutch student, who gained local stardom during the summer of 2007 with his single "Groningen (Het Gras van het Noorderplantsoen)", which means Groningen (The Grass of the Northern Park). The popularity of the song was encouraged by the fact that members of fraternity R.K.S.V. Albertus Magnus promoted the song.
