The mosque exterior, c. 1900.

The Sidi Okba Mosque ( Arabic : مسجد سيدي عقبة , romanized : Masjid Sīdī ʻUqbah)) is a mosque in the village of Sidi Okba, near Biskra, Algeria. A mausoleum was first established here in 686 to house the remains of Uqba ibn Nafi, a companion of the Islamic prophet Muhammad ﷺ and one of the prominent commanders of the Muslim conquest of the Maghreb, making it one of the oldest Muslim monuments in Algeria. The mosque was built around the tomb and has been renovated many times over the centuries. Since 2009, the historic building has been integrated into a much larger modern religious complex.
