Srđa Trifković (Serbian Cyrillic: Срђа Трифковић, Serbian pronunciation: [sr̩̂dʑa trîfkɔʋitɕ]; born 19 July 1954) is a Serbian-American publicist, politician and historian. Trifković was an unofficial spokesman for the Republika Srpska government in the 1990s and a former adviser to Serbian president Vojislav Koštunica and Republika Srpska president Biljana Plavšić. He has argued that the accepted interpretation of the Srebrenica genocide is a "myth based on a lie".
