Lourdes water is water which flows from a spring in the Grotto of Massabielle in the Sanctuary of Our Lady of Lourdes, France. The location of the spring was described to Bernadette Soubirous by an apparition of Our Lady of Lourdes on 25 February 1858. Since that time many thousands of pilgrims to Lourdes have followed the instruction of Our Lady of Lourdes to "drink at the spring and wash in it".

Although never formally encouraged by the Church, Lourdes water has become a focus of devotion to the Virgin Mary at Lourdes. Since the apparitions, many people have claimed to have been cured by drinking or bathing in it,and the Lourdes authorities provide it free of charge to any who ask for it.

The French author Emile Zola visited the Sanctuary in 1891 and again in 1892. He wrote:

And the water was not exactly inviting. The Grotto Fathers were afraid that the output of the spring would be insufficient, so in those days they had the water in the pools changed just twice a day. As some hundred patients passed through the same water, you can imagine what a horrible slop it was at the end. There was everything in it: threads of blood, sloughed-off skin, scabs, bits of cloth and bandage, an abominable soup of ills... the miracle was that anyone emerged alive from this human slime.
