A battle of attrition is a military engagement in which neither side has any tactical advantage, so that the only result of the fighting is the loss of men and materiel on both sides. Battles of attrition can be very lengthy, and test both sides' ability and willingness to make good their losses.

Notable battles of attrition include:

• Battle of Actium of 31 BC during the Roman civil wars.
• Trench warfare in the American Civil War, notably the Siege of Petersburg.
• Trench warfare in World War I, including the Battle of the Somme (1916), the Battle of Verdun and many others.
• Static battles in World War II, including the first phases of the Battle of Stalingrad.
• The War of Attrition between Egypt and Israel.
