The Zawiya of Moulay Idris II is a zawiya in Fez, Morocco. It contains the tomb of Idris II, who ruled Morocco from 807 to 828 and is considered the main founder of the city of Fez. It is located in the heart of Fes el-Bali, the UNESCO-listed old medina of Fez, and is considered one of the holiest shrines in Morocco. The current building experienced a major reconstruction under Moulay Ismail in the early 18th century which gave the sanctuary its overall current form, including the minaret and the mausoleum chamber with its large pyramidal roof.

A zawiya or zaouia is a building and institution associated with Sufis in the Islamic world. It can serve a variety of functions such a place of worship, school, monastery and/or mausoleum. In some regions the term is interchangeable with the term khanqah, which serves a similar purpose. In the Maghreb, the term is often used for a place where the founder of a Sufi order or a local saint or holy man lived and was buried. In the Maghreb the word can also be used to refer to the wider tariqa and its membership.
