Christianity is the official religion in Zambia according to the 1996 constitution, and the vast majority of Zambians are Christians of various denominations, but many other religious traditions are present. Traditional religious thought blends easily with Christian beliefs in many of the country's syncretic churches. Other religions include the Bahá'í Faith, Islam, Hinduism, Sikhism, and Judaism. Ismaili Muslim, Hindu and Sikh communities exist owing to the Indian and Pakistani diasporic community.
In 2010, according to World Christian Trends, 85.5% of the population identified as Christian, 11.2% identified with indigenous religions, 1.8% identified as Bahá'í, 1.1% identified as Muslim, 0.2% identified as agnostic, 0.1% identified as Hindu, and all other groups accounted for less than 0.1%. The 2010 Zambian census found that 75.3% of Zambians were Protestant, 20.2% were Catholic, 0.5% were Muslim, 2.0% followed other religions, and 1.8% had no religion.
Zambia got independence in 1964 from British. Post independence, there were Pentacostal and Charismatic missionaries from the United States during the 70s where the message of the message of God blesses followers with material wealth had a wide audience. The growth of the religion suffered during the 80s and 90s on account of increased economic turmoil. After Frederick Chiluba (a Pentecostal Christian) became President in 1991, Pentecostal congregations expanded considerably around the country. While the initial constitution did not specify religion, the amendment in 1996 declared the nation as "a Christian nation while upholding the right of every person to enjoy the person's freedom of conscience and religion". As per the Article 1 of the constitution, the nation is a Sovereign Secular Republic and as per Article 25, citizens free to express thoughts and practice any religion.
Christianity is believed to have arrived in Zambia in the form of European Protestant missionaries and African explorers during the mid of 19th century. David Livingstone was a Scottish missionary who did pioneering missionary work that brought the attention of Africa to the Western world. Livingstone inspired abolitionists of the slave trade, explorers and missionaries. He led the way in Central Africa to missionaries who initiated the education and health care for Africans. Many African chiefs and tribes held him in high esteem and it was one of the major reasons for facilitating relations between them and the British.
Zambia is officially a Christian nation according to the 1996 constitution, but a wide variety of religious traditions exist. Traditional religious thought blends easily with Christian beliefs in many of the country's syncretic churches. Christian denominations include: Presbyterianism, Roman Catholic, Anglican, Pentecostal, New Apostolic Church, Lutheran, Seventh-day Adventist, Jehovah's Witnesses, The Church of Jesus Christ of Latter-day Saints, Branhamism, and a variety of Evangelical denominations. These grew, adjusted and prospered from the original missionary settlements (Portuguese and Catholicism in the east from Mozambique) and Anglicanism (English and Scottish influences) from the south. Except for some technical positions (e.g. physicians), western missionary roles have been assumed by native believers.
The Bahá'í population of Zambia has been estimated at 162,443, or 1.70% of the population.

Islam arrived in Zambia in the form of Arab slave traders during the mid of 18th century. Other Muslims and people from Hindu community arrived to Zambia during the British Colonial rule. Approximately 1% of Zambians are Muslim, mostly living in urban areas. The vast majority of Muslims in Zambia are Sunni. An Ismaili Shia community is also present. About 500 people in Zambia belong to the Ahmadiyya sect of Islam.
