San Nicolò al Lido refers to both the San Nicolò Church and most importantly to its annexed Monastery of San Nicolò located in Venice, northern Italy. The two Catholic institutions are located in the northern part of the Lido di Venezia and house the relics of Saint Nicholas, patron of sailors. From this church, the traditional thanksgiving Mass of the Sposalizio del Mare is celebrated. The complex houses monks of the Franciscan order.

Life on the Lagoons, which deals with the history and topography of the watery area around the city of Venice, is the first book by the Scottish historian Horatio Brown.
