Hasan Fehmi Bey (1874 – April 6, 1909) was an Ottoman journalist, who was the editor-in-chief of Serbestî, an Ottoman newspaper owned by Mevlanzade Rifat Bey, in which he wrote articles against the newly emerging Committee of Union and Progress (CUP).

[2] On April 6, 1909, Fehmi was murdered by unidentified assailants as he was crossing the Galata Bridge in Istanbul with his friend Şakir Bey, a desposed subgovernor.

On April 8, the front page of Serbestî contained a single line invoking the Al-Fatiha for Fehmi's soul.

The opposing Liberal Party accused the CUP of having Fehmi murdered; others claimed the real perpetrator was from the palace.

[4] He was buried at the tomb (türbe) of Sultan Mahmud II on Divan Yolu Caddesi in Istanbul.
