Nukkariyya (),“Deniers,” also called the Nakkara or al-Nakkariyya or Yazidiyya was one of the main branches of Ibadi Islam, founded in 784 by Abu Qudama Yazid ibn Fandin al-Ifrani. Led by Abu Yazid al-Nukkari, they revolted against the ruling Fatimids in Ifriqiya (today's Tunisia and eastern Algeria), conquering Kairouan in 944 and laying siege to Sousse, but were ultimately defeated in 947. The Nukkari were known as "Yazidiyya" due to their founder, Yazid al-Irfani, and had no connection to the Adawiyya Kurds, who were called Yazidiyya due to their reverence of Yazid ibn Muawiya. Remnants of the Nukkari are thought to have survived on the island of Djerba and zuwara. They split from mainstream Ibadism, i.e. the Wahbi. The parent branch of Nukkari, Wahbi Ibadism, was the most mainstream of the schools of thought within Ibadism, due to the fact that most preserved Ibadi texts can be attributed to Wahbi affiliated scholars.
