Joachim Zachris Duncker was a Swedish soldier born in Ristiina in Savonia.

In 1789 Duncker obtained the rank of 2:nd Lieutenant in the Savonia ranger regiment. He fought in the 1790 war against Russia and proved his valor at the Battle of Perttimäki May 19. In 1804 Duncker was promoted to Captain.

When Cronstedt's army retreated from Mikkeli to Iisalmi and Oulu through Leppävirta, Duncker commanded the army's rearguard. During the Battle of Pulkkila he distinguished himself so well that Johan August Sandels gave him the honorary assignment to bring the news of the victory to the Swedish king. Shortly after, he was promoted to Major. In June 1808 he captured a large transport of supplies to the Russians. During the Battle of Koljonvirta, Duncker together with Colonel Fahlander and Major Malm and only 600 men helped Sandels to utterly defeated a superior Russian force. In 1809 Duncker fought the Russians in the Swedish province of Västerbotten, and was promoted to Lieutenant-Colonel. During the Battle of Hörnefors Duncker commanded the Swedish rearguard and received fatal wounds and died in the Russian encampment the day after.
