Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship.
Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning.
In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam.
Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life, although some modules may have been started months before that stage of construction.

Keel-related traditions from the times of wooden ships are said to bring luck to the ship during construction and to the captain and crew during her later life. They include placing a newly minted coin under the keel and constructing the ship over it, having the youngest apprentice place the coin, and when the ship is finished, presenting the owners with the oak block on which the keel is laid. The tradition of the placement of coins derives from the mast stepping custom of placing coins under the mast and is believed to date back to Ancient Greece or Ancient Rome and were intended to "pay the ferryman" to convey the souls of the dead across the River Styx should the ship sink.
