The Neocatechumenal Way, also known as the Neocatechumenate, or NCW is a program in the Catholic Church. It is inspired by the catechumenate of the early Catholic Church where converts from paganism were prepared for baptism through a process of faith formation. This post-baptismal formation helps deepen the faith for adults that have already been baptized, and provides basic instruction to those that are far from the Church. This itinerary of formation adapts the rites of the Rite of Christian Initiation of Adults (RCIA) for those that have already been baptized, without repeating the sacrament of baptism.

The Neocatechumenate began in Madrid in 1964 by Kiko Argüello and Carmen Hernández. It is implemented in small, parish-based communities of up to 50 people. In 2007 there were around 20,000 such communities throughout the world, with an estimated one million Catholics following the itinerary. The Neocatechumenal Way has always placed a strong emphasis on New Evangelization, administering over 100 missionary diocesan seminaries, as well as sending families in mission around the world, to be a Catholic presence in secularized places.

In the early 1960s, Francisco "Kiko" Argüello moved to the shanty town of 'Palomeras Altas' in Vallecas, Madrid, and gathered a community of Romani people and marginalised poor. He was soon joined by Carmen Hernández, who linked the community to the theological and liturgical zeitgeist surrounding the Second Vatican Council, and won the support of the archbishop of Madrid Casimiro Morcillo González [es], who had been a relator during sessions of the Council.

Gradually, the community's approach was codified in a "catechetical synthesis" referred to as the "tripod," "Word of God-Liturgy-Community", with the stated aim of seeking to lead people to fraternal communion and mature faith.^{[citation needed]}

The movement spread through the Archdiocese of Madrid and to other Spanish dioceses. In 1968, it began to spread beyond Spain when Argüello and Hernández arrived in Rome and settled in the Borghetto Latino.^{[citation needed]}

The community of Neocatechumens was led by the "International Responsible Team of the Way": Argüello, Hernández, and Fr. Mario Pezzi, a priest of the Diocese of Rome, until Hernández's death, in 2016. Under the terms of the 2007 statute, the three members of this leadership team will remain in place for life, after which an electoral college of senior neocatechumenal catechists will elect a new team which, with the approval of the Pontifical Council for the Laity, will have a mandate to lead the Way for a period of seven years until new elections are held. The Neocatechumenal Way announced on 13 February 2018 that María Ascensión Romero had been chosen to join the leadership team.

"They contribute by forming the first neocatechumenal communities of a parish, and are supposed to maintain regular contact with the Bishops of the diocese in which they work; the itinerant teams preserve a constant link with the responsibles of the Neocatechumenal Way, visiting periodically the communities they catechized and taking care of the development of the Neocatechumenal Way in the territory assigned to them, being fully faithful to the charism given to the initiators and obedient to the local Ordinary."

The Neocatechumenal Way as it has been approved by the Holy See is a "Post baptismal catechumenate at the service of the Bishops as a form of diocesan implementation of Christian initiation and of ongoing education in faith, in accordance with the indications of the Second Vatican Council and the Magisterium of the Church”. From the initial catechesis, it typically takes several years and passing through stages of faith formation in the local communities, until a member reaches the "renewal of the baptismal vows."^{[citation needed]}
