Cecilia de Madrazo y Garreta (20 December 1846, in Madrid – August 1932, in Venice) was a collector of textiles. She was married to the famous Spanish artist, Marià Fortuny.

She was born into a family of artists. Her father, Federico de Madrazo and grandfather, José de Madrazo, were both painters. Her grandmother, Isabel Kuntz Valentini was a daughter of the Polish painter, Tadeusz Kuntze. In addition, her uncles, Pedro de Madrazo and Luis de Madrazo were painters, and both of her brothers, Raimundo de Madrazo and Ricardo de Madrazo, would become painters as well.

As a child, she became an accomplished pianist and performed at various artistic gatherings and musical events. In 1867, she married Marià Fortuny, an artist who had already won considerable fame throughout Europe and, thanks to his financial success, was also a collector of art, weapons, ceramics and textiles. As his wife, she collaborated with him on seeking out antiquities and became a popular figure in the artistic circles that gathered around him. They had two children, María Luisa and Mariano Fortuny, who became a noted photographer and fashion designer. He also inherited his mother's passion for textiles.

She circulated throughout Madrid, Granada, Rome, París and Venice. In 1875, following the death of her husband a few months before, she and her children moved to Paris. In 1889, the family moved to what would be her last residence, the Palazzo Martinengo in Venice.
