Saint Peter and Saint Paul is a significant holiday in Chile, observed annually on June 29th. The day is dedicated to remembering the lives and deeds of the apostles Saint Peter and Saint Paul, who played foundational roles in the early Christian Church. Chile, being a predominantly Catholic country, gives much importance to this feast as these apostles represent the roots of their faith.

On this day, varied eccentric and colorful festivities can be witnessed throughout the country. The maritime communities of Chile, in particular, celebrate Saint Peter, the Patron Saint of fishermen, with local seafaring processions. These include decorating boats with flags and flowers, which then carry the image of Saint Peter through the sea. This tradition resonated from the belief that Saint Peter guides the fishermen and protects them from the dangers at sea.

Aside from the maritime processions, Holy Masses and church services are held in honor of the apostles. Families also get together on this day as it is a public holiday, giving them an opportunity to spend time together and participate in the festivities. Regardless of an individual's religious affiliation or beliefs, the holiday invites everyone to enjoy and appreciate the strong cultural heritage and tradition of Chile as it apportions the values of unity, bravery, and devotion, as exemplified by Saints Peter and Paul.
