Operation Southern Focus was a period in the months leading up to the 2003 invasion of Iraq (called "Operation Iraqi Freedom" in the United States) in which the military responses to violations of the southern Iraqi no-fly zones were increased, with more intensive bombing of air defense artillery installations and other military complexes. It also marked a period of increased intelligence gathering. The operation lasted from June 2002 until the beginning of the invasion in March 2003. It was intended to be a "softening up" period prior to invasion, degrading Iraq's air defense and communication abilities. Lieutenant General T. Michael Moseley revealed the operation's existence in mid-2003.
