Georgios Doitsinis (Greek: Γεώργιος Δοϊτσίνης) was a significant Greek chieftain of the Greek Struggle for Macedonia. Doitsinis was born in the 1880s in Matsikovo (renamed Evzonoi in 1927) of Kilkis. He was the grandson of the Kodjabashi of Matsikovo Georgios Doitsinis, who had successfully defended several early Bulgarian activities. He was one of the first revolutionaries to set up an armed group in the areas of Bogdanci and Gevgelija, cooperating with the Greek Center of Thessaloniki since the autumn of 1904. His group consisted of local Macedonian and Cretan soldiers. He cooperated with chieftains Michael Sionidis, L. Papamalekos and Em. Katsigaris.
