Apostol Petkov Terziev (Bulgarian/Macedonian: Апостол Петков Терзиев; May 6, 1869 – August 2, 1911) was a Macedonian Bulgarian revolutionary and one of the leaders of the national liberation movement in Ottoman Macedonia.

Apostol was illiterate but found a job working as a cantonment officer on the Thessaloniki-Skopje railway line, where he remained until 1892 when he decided to become a rebel.

By the time of the Ilinden–Preobrazhenie Uprising in 1903, Apostol Petkov had become Voivode, of an armed group around the town of Giannitsa, where he took an active part in the rebellion.

In August 1904, Apostol would seek revenge for death of fellow Komitadji Tsiopkas and his band who had been killed by the Ottomans following notification from the Greek Consulate of Thessaloniki.

In early March 1905, the band of Apostol Petkov and another of Sava Mihaylov numbering 42 Komitadjis in total, were surrounded at the village of Gevgelija Smoli (Mikro Thasos) by the Ottoman army and Bashi-bazouks.

By the end of 1905, Apostol was involved in many attempts to forcefully convert the allegiances of villages from the Patriarchate to the Exarchate with demands that local Greeks declare themselves Bulgarian or face his consequences.

[7] From 1906 - 1908, Voivoda Apostol and his Komitadjis would come to blows with the band of Kapetan Alexandros Mazarakis-Ainian (Akritas) and other Greek chieftains in various battles.

Apostol Petkov was pardoned following the Young Turk Revolution, However, he was disappointed in the new policy that was put in place and went to Bulgaria in 1910.
