Osman Oktay Ekşi (born 7 December 1932) is a Turkish journalist, author and politician. He has spent much of his career at the newspaper Hürriyet, and was its Chief Columnist from 1974 to 1983 and from 1985 to 2010. A founding member and vice chairman of the Social Democratic Party (SODEP), he was elected as a member of Parliament for the Republican People's Party (CHP) in the 2011 general election.
 He started his journalism career as a reporter for the Ankara News Agency (ANKA) in 1952. Between 1952 and 1954, he was the Ankara Correspondent for Dünya ("World"), a daily newspaper. He served as Ankara Bureau Chief of Dünya between 1954 and 1960.
 After serving as local secretary at the Turkish Consulate General in London from 1962 to 1996, he returned to Turkey in 1966 to take up a job as Ankara bureau chief of Yeni Gazete daily (an affiliate of Hürriyet daily) which lasted until 1970.  After working one year (between 1970-1971) at the Turkish Radio and Television Network (TRT) he joined Hurriyet newspaper in 1971 in Ankara as a correspondent at large. He became Ankara bureau chief in 1972, and in 1974 he was appointed as the chief (leading) columnist of Hürriyet. He fulfilled this position until 1983, during which time (between 1974 and 1982) he was general manager of Hürriyet News Agency ("Hürriyet Haber Ajansı").
 In 1984, Ekşi became chief (leading) columnist of Güneş daily but rejoined Hürriyet which had the largest circulation of any Turkish paper in 1985, serving as chief (leading) columnist until 2010. In 2010 Oktay Ekşi resigned from Hürriyet daily when one of his articles was taken as a personal insult by the then Prime Minister. Ekşi wrote that the plan to build hydroelectric complexes in hundreds of locations in Turkey, including Rize reflected a “mindset of one willing to sell his own mother”.  The then Prime Minister Recep Tayyip Erdoğan, Energy and Natural Resources Minister Taner Yıldız and Environment and Forestry Minister Veysel Eroğlu reacted negatively to this criticism.
 From 1988 to 2010, Oktay Ekşi was the chairman and leading founding member of the (Turkish) Press Council.
