Nicholas the Pilgrim (Italian: Nicola il Pellegrino; Greek: Άγιος Νικόλαος ο Προσκυνητής; 1075 – 2 June 1094), sometimes Nicholas of Trani, is a saint of the Roman Catholic and Eastern Orthodox Church.

Nicholas was born at Steiri in Boeotia, Greece, where his solitary life as a shepherd led him to contemplative spirituality, as part of which he developed the constant repetition of the phrase Kyrie Eleison.

[5] His mother, believing that he was possessed by demons, sent him to live at the Hosios Loukas monastery but the monks became annoyed with his almost insane behaviour, such as the constant exclamation of the Kyrie Eleison, and expelled him.

[4] In Naupaktos he embarked on a ship to Otranto and spent some time in the Greek-populated regions in Apulia before dying in Trani[6] Three years after Nicholas' death, archbishop Bisantius of Trani commissioned the building of a new cathedral dedicated to Nicholas and asked in 1098/99 while participating in the Lateran council Pope Urban II for his permission for the sanctification of Nicholas.

[7] Nicholas' life is known primarily from three sources, of which the earliest was written three years after his death based on information provided by his travel companion Bartholomew.
