The Sanctuary of Fátima (Portuguese: Santuário de Fátima), officially titled Sanctuary of Our Lady of the Rosary of Fátima (Santuário de Nossa Senhora do Rosário de Fátima), but also known as Shrine of Our Lady of Fátima, is a group of Catholic religious buildings and structures in Cova da Iria, in the civil parish of Fátima, in the municipality of Ourém, in Portugal.

In addition to the Basilica of Our Lady of the Rosary (Basílica de Nossa Senhora do Rosário), the shrine consists of the Chapel of the Lausperene (Capela do Lausperene), a great oak tree near where the 1917 Marian Apparitions occurred, a monument to the Sacred Heart of Jesus (Monumento ao Sagrado Coração de Jesus) and the Chapel of the Apparitions (Capelinha das Aparições) which contains the area where three children, Lúcia dos Santos and her cousins, Francisco and Jacinta Marto, said they were first visited by the Virgin Mary. In addition, several other structures and monuments were built in the intervening years to commemorate the events.
