The towns of Saint-Raymond, Quebec, Canada; San Ramón de la Nueva Orán, Argentina; São Raimundo Nonato, Brazil; San Ramón in Costa Rica are named for him.
A shrine in Buenos Aires and the Roman Catholic Diocese of São Raimundo Nonato (Raymundianus) in Brazil are dedicated to him.

In the United States, the Parish of St. Raymond, in the New York City Borough of the Bronx; the Cathedral of St. Raymond Nonnatus in Joliet, Illinois;  and St. Raymond Catholic Community in Downey, California;  are under his patronage.
There is also a parish dedicated to him in Juana Díaz, Puerto Rico.

Due to the story of his own birth, Raymond quickly became widely invoked by women facing childbirth.

Because of his limited historical importance, however, since the reforms of the Church calendar in 1969, the liturgical commemoration of Raymond's feast day is no longer included among those to be necessarily observed wherever the Roman Rite is celebrated, but, since he is included in the Roman Martyrology for August 31, Mass and the Liturgy of the Hours may be recited in his honor on that day as in the pre-1970 General Roman Calendar, which is observed by some traditionalist Catholics.

One particular devotion is centered around the padlock that is part of his martyrdom.
Locks are placed at his altar representing a prayer request to end gossip, rumours, false testimonies and other sins of the tongue.
The locks are used as a visible sign of such prayer request, which first and foremost must take place interiorly, a prayer to God through St. Raymond's intercession.
