The XVI SS Army Corps was a short-lived corps of the Waffen-SS, which was formed in January 1945 in Pomerania.
The core of the corps was the 1st Latvian SS Division. It fought in the Piła (Schneidemühl) - Bydgoszcz (Bromberg) area against the Soviet East Prussian offensive and was dissolved in February after the retreat from that area.
The corps' only commander was SS-Obergruppenführer Karl Maria Demelhuber.
