Inflation in Bali is high compared with other countries. This study is an investigation of the determinants of inflation in Bali for the period 2000-2014. To analyse the influence of the determinant factors of inflation authors have applied regression analysis by Eviews 6. Our study has found that such factors, as foreign exchange, bank interest rate, the size of government expenditure, the size of public expenditure have no influence on inflation. Researchers have suggested the government to focus not only on monetary policy but also on other techniques and policies that would encourage the supply of goods, would avoid deficit and would contribute to maintaining stable oil prices in Bali.
