Radikal (lit. 'Radical') was a daily liberal Turkish language newspaper, published in Istanbul. From 1996 it was published by Aydın Doğan's Doğan Media Group. Although Radikal did not endorse a particular political alignment, it was generally considered by the public to be a social liberal newspaper. Despite only having a circulation of around 25,000 (July 2013), it was considered one of the most influential Turkish newspapers.
