Egypt is predominantly Muslim, with Muslims comprising between 80% and 90% of a population of around 80 million Egyptians. Almost the entirety of Egypt's Muslims are Sunnis. Most of the non-Muslims in Egypt are Christians, around 95% of whom belong to the native Coptic Orthodox Church of Alexandria.

Of the Ancient Egyptian religion no adherents still exist. Practically all Muslims are Sunni. The Christians are mainly Copts, divided into two groups, the one having close organizational ties to the Roman Catholic Church. There are other small Christian groups, standard Roman Catholics, Greek Orthodox, and Armenian Orthodox, in Alexandria and Cairo, whose adherents are mainly descendants of Italian, Greek, and Armenian immigrants. There are also some few, small Jewish communities.
