Most Argentines identify as Catholic, so churches, saints’ days, and religious processions are familiar parts of public life, but everyday society is generally secular and people do not expect visitors to participate in religious observance. If you are invited to a family celebration or a local festival, it is polite to be respectful during Mass or a procession, and you may also encounter strong devotion to figures such as the
Virgen de Luján alongside a growing evangelical presence.
