Nikolaos Delagrammatikas (Greek: Νικόλαος Δελαγραμμάτικας, born 1853) was a senior Hellenic Army officer who fought in the Greco-Turkish War of 1897 and the Balkan Wars of 1912–1913. He was born in Chalkis in 1853, and enlisted in the Hellenic Army as an NCO. In 1878, as a sergeant, he fought in the cross-border incursion into Ottoman territory that resulted in the battle of Gribovo, and again in the border skirmishes of 1886, this time as a Second Lieutenant. He is the father of Vice Admiral (1876–1947).
