The bombing of Romania in World War II comprised two series of events: until August 1944, Allied operations, and, following the overthrow of Ion Antonescu's dictatorship, operations by Nazi Germany.
The primary target of Allied operations was Ploiești, the major site of Romania's oil industry. The largest refinery there—Astra Română—processed 2,000,000 short tons (1,800,000 t) of petroleum a year, providing much of the fuel for the German military. Other attacks were against Bucharest, the country's capital.
