The Notitia de servitio monasteriorum ("Notice of the Service of Monasteries") is a list of monasteries in the Frankish Empire and the services they owed the crown. It was compiled under Emperor Louis the Pious in 819, probably as a summation of the royal reform of the monasteries carried out following the councils of 816 and 817. It is not a complete list of the reformed monasteries: only 82 of the 104 monasteries known to have adopted the reforms are listed in the Notitia.
