Luxembourg will participate in the North Vision Song Contest 23 with a to-be-determined song written by to-be-determined songwriters. The song will be performed by a to-be-determined artist. The Luxembourgian broadcaster RTL Télé Lëtzebuerg (RTL) organised the national final TBA in order to select the Luxembourgian entry for the twenty-third edition in a to-be-determined city. Ten entries competed in a show that took place on TBA 2017 and the winner was determined over two rounds of public televoting. The top four entries in the first round of voting advanced to the competition's second round—the Gold Final. In the second round of public televoting, "TBA" performed by TBA was selected as the winner with votes.
