Hüseyin Cahit Yalçın (7 December 1874 – 18 October 1957) was a prominent Turkish theorist, writer, and politician.

After the Second Constitutional Era, he helped Tevfik Fikret and Hüseyin Kâzım to publish the Tanin newspaper, as it was put into political life.

[3] He escaped to Romania during the 31 March Incident since the rebels had hoped to kill him, but they confused Mehmet Aslan Bey for him and murdered him instead.

Even though he was opposed German influence in the past, he joined the German-Turkish Association [de] which would support the cultural and economic exchange between the two empires in 1915.

[5] After the defeat of the Ottoman Empire in the First World War, Hüseyin Cahit was exiled to Malta by the British authorities and kept there until 1922.

Hüseyin Cahit promoted liberal democracy and attacked the government for imposing a tight control over society and culture.

After Atatürk's death in 1938, Hüseyin Cahit was invited to join the Republican People's Party by İsmet İnönü, and he was elected to the Parliament of Turkey.

In his article dated 3 December 1945, he attacked the Tan newspaper and Sabiha Sertel for supporting communism and the USSR.
