The speech, to be delivered at 8 p.m. ET, will last approximately 15 minutes. Obama's remarks will also touch on Afghanistan and the broader war against terrorism, the White House said.
Obama will likely visit a military base on Tuesday prior to delivering the address.
The August 31 speech is timed to coincide with the official end of the U.S. military's combat mission in Iraq. The total number of U.S. troops in Iraq has now fallen below 50,000 - the lowest level since the U.S-led invasion in 2003. The remaining American troops will train, assist and advise the Iraqis.
All American troops are scheduled to pull out at the end of 2011, though the Iraqi government could request that some of them remain.
Obama has delivered one previous Oval Office address, to signify the gravity of the Gulf of Mexico oil spill in early June.
