The Neocatechumenal Way, also known as the Neocatechumenate, NCW, colloquially The Way, is an itinerary of Christian formation within the Catholic Church. It was formed in Madrid in 1964 by Kiko Argüello and Carmen Hernández. Taking its inspiration from the catechumenate of the early Catholic Church by which converts from paganism were prepared for baptism, it provides post-baptismal formation to adults who are already members of the Church or to those far from the Church who have been attracted by the testimony of Christian life of love and unity in the communities (referencing such Bible verses as John 13:35 and John 17:21), in accordance with the designs of the Rite of Christian Initiation of Adults (RCIA).

The Neocatechumenate, as an itinerary 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 million Catholics following the itinerary. Due to numerous vocations coming from the families formed in the communities, it has also helped to establish and run over 100 missionary diocesan seminaries in various locations. They are called "Redemptoris Mater" seminaries. It is responsible for communities of "families in mission", called "Missio ad gentes", living in many cities around the world. Together with a priest and his socius, and some celibate women, they make present the Church in places of little or no Catholic presence.
