The Monastery of Santa Maria de Poblet, known in Catalan as Reial Monestir de Santa Maria de Poblet and commonly called simply Poblet, represents the model par excellence of Cistercian abbey in Spain.

It is located in the region of the Cuenca de Barberá, in the municipality of Vimbodí i Poblet, in the province of Tarragona. Its foundation was promoted by Ramón Berenguer IV, Count of Barcelona, who in 1149 gave it to the Cistercian monks from the Fontfroide Abbey. From the end of the 14th century until the disappearance of the royal dynasty of Aragon in the 15th century, it served as the pantheon of the Crown of Aragon.

Thanks to various donations, the monastery reached its greatest splendor in the 14th century. However, it fell into decline and was abandoned in 1835 after the disentailment of Mendizábal. In 1930 it began to be restored, allowing religious services to be resumed in the church in 1935, and in 1940 some monks returned to monastic life. Currently, certain areas of the monastery are not open to the public, as they are destined for the enclosure of the Cistercian community that once again resides there.

In 1991, UNESCO included it in its list of World Heritage Sites. Poblet is part of the select group of Spanish monasteries with this distinction, along with Guadalupe, El Escorial, San Millán de Yuso and San Millán de Suso.
