The St.-Martins-Chorknaben Biberach is a boys' and men's choir from Biberach an der Riß in southern Germany. The choir was founded in 1962 and has since been a member of the Pueri Cantores, an international association of Catholic youth choirs. The choir regularly takes part in services in its home parish St Martin and the surrounding parishes. On their annual concert tour, the choirboys also perform abroad.
