The Aguirre School (Escuelas Aguirre), today also known as the Casa Árabe (Arabic House), is a notable Neo-Mudéjar style building, located at Calle de Alcalá, 62, Madrid, Spain. It is named after Lucas Aguirre, a Spanish philanthropist who left funds for the construction of schools. Since 2006 it has housed the Casa Árabe e Instituto Internacional de Estudios Árabes y del Mundo Musulmán.
This Neo-Mudéjar style building was designed by Emilio Rodríguez Ayuso and built from 1881-1886. The same architect later added an enclosure (1887) and garden (1896–98). Subsequently architect Luis Bellido González performed alterations in 1908–1909 and 1929, with a third set of alterations and basement extension made by Antonio Flórez Urdapilleta and Bernardo Giner de los Ríos in 1932–1933.
