The Fossar de les Moreres (, literally "Grave of the Mulberries") is a memorial square in Barcelona (Catalonia, Spain), adjacent to the basilica of Santa Maria del Mar. The plaza was built over a cemetery where defenders of the city were buried following the Siege of Barcelona at the end of the War of the Spanish Succession in 1714. The plaza retains its everyday use as a public space, but also prominently features a memorial to the fallen Catalans of the war, with a torch of eternal flame and a heroic poem by Frederic Soler, "El Fossar de les Moreres".
