The Actions along the Matanikau were the two most prominent engagements across the Matanikau River in Guadalcanal during World War II. In the first of these separate but related actions (23–27 September 1942), elements of three U.S. Marine battalions attacked Japanese troop concentrations around the river. The attack was intended to destroy any Japanese forces in the area and to disrupt their attempts to stage attacks on the Marine's defenses at Lunga Point by denying their use of Point Cruz peninsula, the village of Kokumbona, and a series of ridges and ravines stretching inland from the coast. The Japanese repulsed this attack. In the second action (6–9 October), a larger force of Marines crossed the river and inflicted heavy casualties on an infantry regiment. This forced the Japanese to retreat from their positions east of the Matanikau and hindered their preparations for a planned major offensive on the U.S. Lunga defenses set for later in October.
