The aim of this paper is to investigate the impact of government size on unemployment rate in Iranian economy. By using the model of Christopoulos, Loizides & Tsionas (2005), the relationship between government size and unemployment has been investigated during 1974-2012. The results of threshold model indicate that when the government size is less than 0.2484, increasing of government size has a significant negative impact on unemployment but after the mentioned threshold value, due to crowding out effect of government intervence, government size has a significant positive impact on unemployment. Also, the results of estimation show that inflation has a significant negative impact on unemployment that confirms Philips curve in Iranian economy.   Unemployment is one of the most important challenges of Iranian economy that affects the society and economic performance.
