What is the name of the traditional song sung on Saint Lucia's Day?

The traditional song associated with Saint Lucia’s Day is “Santa Lucia.” It is a traditional Neapolitan song whose melody is used for Lucia processions, particularly across Scandinavia.

The original song was not written specifically for the saint’s feast. It celebrates Borgo Santa Lucia, a waterfront district in Naples, and invites listeners to enjoy a boat ride on the calm bay. Teodoro Cottrau translated the Neapolitan lyrics into Italian and published the song in Naples in 1849.

Scandinavian countries adapted the melody with local Saint Lucia lyrics about carrying light through winter darkness. Sweden has several versions, including “Natten går tunga fjät” and “Sankta Lucia, ljusklara hägring.” Thus, local lyrics may differ, but “Santa Lucia” identifies the traditional tune and song most commonly linked with the celebration.
