Good Friday is a prominent Christian holiday in Argentina, remembering the crucifixion of Jesus Christ, and his death at Calvary. This comes as a part of the Holy Week celebrations, leading up to Easter Sunday. It is observed during the Holy Week on the Friday preceding Easter Sunday. As Argentina is a country with a majority Catholic population, Good Friday is a public holiday and is marked by a number of religious and cultural traditions.

On Good Friday, Argentinians participate in various religious rituals and customs. One of the most common traditions involves processions through the streets of various cities, most notably in Tandil and Buenos Aires, where large-scale Passion Plays are acted out, retracing the steps of Jesus's suffering. The streets often echo with religious hymns and prayers as believers join the solemn march, carrying crosses and religious icons.

Beyond processions and masses, Good Friday in Argentina is often a day of quiet observance and contemplation for many families. It is a common custom to abstain from consuming meat and to prepare meals featuring fish and other seafood instead. Some families also use the long holiday weekend as an opportunity to travel within the country, supporting local tourism and enjoying the Argentinian autumn. Despite the solemnity of Good Friday, the observance of the holiday typically ends with a celebratory meal on Easter Sunday, symbolizing the resurrection of Christ.
