Canillejas is a suburb of Madrid, Spain, lying to the east of the city. It is located in San Blas district which formerly composed the old town of Canillejas that was annexed to Madrid in 1949.  The Fiestas de Canillejas takes place from the 1 to 7 of September. Canillejas is one of the last stations on the number 5 line of the Madrid Metro.
Canillejas is a middle class area and is close to the Barajas Airport. It has grown extensively in the last two decades. It was the last suburb before reaching the Campos (countryside), but has since been flanked by new growth. Heading towards the center of the city, its main street becomes the Calle De Alcalá on which many of Madrid's landmarks are including the bullring, Retiro Park and eventually ending in Puerta del Sol.
