Christianity is the most widely professed religion in Peru, with Catholicism being its largest denomination.
Religion in Peru is traditionally related to religious syncretism originating from Catholicism with the ancient Inca religion after the Spanish Conquest. However, Protestant churches of various denominations have developed considerably in the popular sectors over the past 30 years. There has been a slow but consistent advance of irreligion especially among young people in urban areas. Religions such as Judaism and Buddhism, and more recently Hinduism and Islam, are present due to immigration.
According to article 2 of the Peruvian Constitution: "Everyone has the right to freedom of conscience and religion, individually or in association. There is no persecution for reasons of ideas or beliefs. There is no crime of opinion. The public exercise of all confessions are free, as long as they do not offend morals or disturb public order."

History
The Spanish conquerors not only conquered Peru militarily, but also sought to convert the indigenous populations to Christianity. Indigenous Andean religious beliefs and practices persisted, which the Catholic Church sought to suppress. Many churches were built in the colonial period, the visible manifestation of Catholicism. Some convents were also built on Inca sites. For example, in 1605, some Dominican nuns built the Convent of Santa Catalina in Cuzco atop the site of the "acllahuasi", once home to virginal young women dedicated to serving the ruling Inca. Another convent, the Convent of Santa Clara, was one of the first institutions the conquistadores of Cuzco built for "Indian nobles", the daughters of the indigenous elite whose collaboration made Spain's indirect rule over the Andes possible. At Santa Clara, Inca nobles were to be "raised Christian and to receive 'buenas costumbres' (literally, good customs or manners), shorthand for an education in Spanishness", which included knowledge, stitchery, and literacy. After graduating from this course in Spanish culture, charges were free to profess vows or leave the convent. Miscegenation was not an issue among Spaniards. Many prominent Spanish men lived with elite Inca women, only to marry Spanish women later in life and marry off their Andean partners to less prominent Spaniards.
Modern era
The Peruvian government is closely allied with the Catholic Church. Article 50 of the Constitution recognizes the Catholic Church's role as "an important element in the historical, cultural, and moral development of the nation." Catholic clergy and laypersons receive state remuneration in addition to the stipends paid to them by the Church. This applies to the country's 52 bishops, as well as to some priests whose ministries are located in towns and villages along the borders. In addition each diocese receives a monthly institutional subsidy from the Government. An agreement signed with the Vatican in 1980 grants the Catholic Church special status in Peru. The Catholic Church receives preferential treatment in education, tax benefits, immigration of religious workers, and other areas, in accordance with the agreement. So Roman Catholicism could be considered the main religion of Peru.

Although the Constitution states that there is freedom of religion, the law mandates that all schools, public and private, impart religious education as part of the curriculum throughout the education process (primary and secondary). Catholicism is the only religion taught in public schools. In addition, Catholic religious symbols are found in all government buildings and public places.
According to the 2017 Census, there were 76% of the population aged 12+ identifying themselves as Catholics.
Protestantism
Since the 1990s, Evangelicalism has experienced growth in Peru, with many Evangelical leaders promoting Alberto Fujimori during the 1990 Peruvian general election and were members of his political party, Cambio 90. As of the 2017 Census there were 14.1% of the population aged 12+ identifying themselves as Protestants, mainly Evangelicals. In Latin America most Protestants are called Evangelicos because most of them are Evangelical Protestants, while some are also traditional Mainline Protestant. They continue to grow faster than the national growth rate.
