The Naval Battle of Guadalcanal took place from 12 to 15 November 1942 and was the decisive engagement in a series of naval battles between Allied and Imperial Japanese forces during the months-long Guadalcanal campaign in the Solomon Islands during World War II. The action consisted of combined air and sea engagements over four days, most near Guadalcanal and all related to a Japanese effort to reinforce land forces on the island. The only two U.S. Navy admirals to be killed in a surface engagement in the war were lost in this battle.
