The Battle of Tripoli, sometimes referred to as the Fall of Tripoli, was a military confrontation in Tripoli, Libya, between loyalists of Muammar Gaddafi, the longtime leader of Libya, and the National Transitional Council, which was attempting to overthrow Gaddafi and take control of the capital. The battle began on 20 August 2011, six months after the First Libyan Civil War started, with an uprising within the city; rebel forces outside the city planned an offensive to link up with elements within Tripoli, and eventually take control of the nation's capital.

The Libyan civil war or the 2011 Libyan revolution, also known as the First Libyan Civil War was an armed conflict in 2011 in the North African country of Libya that was fought between forces loyal to Colonel Muammar Gaddafi and rebel groups that were seeking to oust his government. The war was preceded by protests in Zawiya on 8 August 2009 and finally ignited by protests in Benghazi beginning on Tuesday, 15 February 2011, which led to clashes with security forces who fired on the crowd. The protests escalated into a rebellion that spread across the country, with the forces opposing Gaddafi establishing an interim governing body, the National Transitional Council.
