Santa Marķa la Real de La Almudena is a Catholic cathedral in Madrid.

Plans for the construction of a new cathedral for Madrid dedicated to the Virgin of Almudena began in the 16th century, but the slow construction did not begin until 1879, and was not completed until 1993, when the cathedral was consecrated by Pope John Paul II. Construction ceased completely during the Spanish Civil War, and throughout time involved several different architects. On May 22, 2004, the marriage of Felipe, Prince of Asturias to Letizia Ortiz Rocasolano (who was thereafter known as Letizia, Princess of Asturias) took place at the cathedral.
