"The Eddie", also known as The Eddie Aikau Big Wave Invitational, is a big wave surfing tournament held at Waimea Bay on the north shore of Oahu, Hawaii. The tournament is named for native Hawaiian, champion big wave surfer, and life-saving Waimea Bay lifeguard, Eddie Aikau. Created in 1984 at nearby Sunset Beach, the invitational tournament moved to the notoriously big waved Waimea Bay, where Aikau's family maintains an ancestral tradition as caretakers of the Waimea Valley. It was formerly known as the Quiksilver in Memory of Eddie Aikau after its sponsor Quiksilver, but the company and the Aikau family could not agree to terms for a new contract after the previous one expired in 2016.

Big wave surfing is a discipline within surfing in which experienced surfers paddle into, or are towed into, waves which are at least 20 feet high, on surf boards known as "guns" or towboards. Sizes of the board needed to successfully surf these waves vary by the size of the wave as well as the technique the surfer uses to reach the wave. A larger, longer board allows a rider to paddle fast enough to catch the wave and has the advantage of being more stable, but it also limits maneuverability and surfing speed.
