Cevat Şakir Kabaağaçlı (17 April 1886, in Crete – 13 October 1973, in İzmir) (birth name Musa Cevat Şakir; pen-name exclusively used in his writings, "The Fisherman of Halicarnassus", in Turkish: Halikarnas Balıkçısı) was a Turkish writer of novels, short-stories and essays, as well as being a keen ethnographer and travelogue.
He is deeply associated with Bodrum where he started to live in 1925 when he was sentenced to three-years' exile, and he fell under the spell of the town. After serving the last part of his sentence in Istanbul, he returned and settled down in Bodrum where he lived for 25 years, whence his pen-name in reference to Halicarnassus, name of the city in antiquity. He is largely credited for bringing the formerly sleepy fishing and sponge-diving town of Bodrum, as well as the entire shoreline of the Blue Cruise, to the attention of the Turkish intelligentsia and the reading public first, and by extension, for paving the way towards the formation of international tourist attraction the region became.
Cevat Şakir had a deep impact on the evolution of intellectual ideas in Turkey during the 20th century. An erudite and colorful person, he remains a figure of reverence.
