The Madrasa Bou Inania (also Bu Inaniya) in Fes, Morocco, is a madrasa founded in AD 1351–6 by Abu Inan Faris who also founded the Madrasa Bou Inania in Meknes.

It is widely acknowledged as a marvel of Marinid architecture. "Bou Inania" comes from the first part of the sultan's name "Abou Inan". The madrasa functioned as both an educational institute and as a congregational mosque at the same time. It is the only madrasa in Fes which has a minaret. Opposite the main doorway of the madrasa is the entrance to the dar al-wudu (ablutions house). Left and right of the central court are class rooms.

According to history religious leaders of the Karaouine Mosque advised Abu Inan Faris to build this Madrasa. It was the last madrasa to be build by the Marinids. The madrasa became one of the most important religious places of Fes and Morocco, gaining the status of Grand Mosque.

The madrasa is one of the few religious places in Morocco that is accessible to non-Islamic tourists.
