The Clonbanin ambush was an ambush carried out by the Irish Republican Army (IRA) on 5 March 1921, during the Irish War of Independence. It took place in the townland of Clonbanin (a.k.a. Cloonbannin), County Cork. The battle lasted slightly over an hour. As the IRA forces withdrew from one side of the road, a British officer and six soldiers attempted to flank the IRA on the other side. After a brief exchange of fire they retreated. The IRA are not believed to have sustained any casualties.
