Corpus Christi, known locally as 'Día de Corpus', is observed in Timor-Leste, a Southeast Asian nation. This holiday is typically celebrated on the Thursday after Trinity Sunday and is a public holiday across the country. The day holds great religious significance for the predominantly Roman Catholic population of Timor-Leste, as it commemorates the Eucharist, a sacrament that represents the body and blood of Jesus Christ.

The celebration of Corpus Christi in Timor-Leste is marked by elaborate religious processions and festivities. The day is started with a mass in the church; following that, a grand procession takes place, wherein the Blessed Sacrament is carried through the streets. These processions usually take place in the capital, Dili, and across various other towns and villages in the country, showcasing colourful decorations and traditional music.

The Corpus Christi celebration also includes local cultural elements. In many communities, beautifully decorated 'carpets', made of sawdust and flowers, are laid out on the streets for the processions to pass over. Additionally, it's a day for families to come together for a shared meal or other social gatherings. Thus, Corpus Christi serves not only as a religious observance in Timor-Leste but also an integral part of their cultural tradition, fostering unity among the people.
