Sunni Islam is the dominant religion in Jordan. Muslims make up about 97.2% of the country's population. A few of them are Shiites. Many Shia in Jordan are refugees from Syria, Lebanon, and Iraq.

Jordan contains one of the oldest Christian communities in the world, their presence dating back to the crucifixion of Jesus Christ early in the 1st century AD. Christians today make up about 3% of the population. Jordanian Christians in a country of almost 10 million are thought to number 250,000-400,000, down from 20% in 1930, but their absolute numbers have increased. This is due to high immigration rate of Muslims into Jordan, higher emigration rates of Christians and higher birth rates for Muslims. All Christian religious ceremonies are allowed to be publicly celebrated in Jordan.
