Corpus Christi is a significant holiday observed in the principality of Liechtenstein. It is celebrated annually on the Thursday following Trinity Sunday, which is the Sunday after Pentecost. The holiday, whose name in Latin means 'Body of Christ', dates back to the 13th century and is a Catholic feast celebrating the Eucharist, understood to be the actual body and blood of Christ. The date of the Corpus Christi holiday varies each year, but it is typically in late May or early June.

The people of Liechtenstein, a predominantly Roman Catholic country, celebrate Corpus Christi with religious processions and masses. These processions often involve large numbers of people and can take on quite a festive air, including music, songs, and sometimes dances. Devotees also decorate the streets with flowers and banners, adding to the festive and reverential atmosphere. City centers, streets, and churches usually have special decorations for this holiday.

Corpus Christi is considered a public holiday in Liechtenstein. Businesses, schools, and government offices are typically closed allowing the populace to fully participate in the festivities. The holiday not only caters to religious practices but also strengthens the sense of community among the inhabitants. Despite being a traditional Catholic holiday, even those who are not members of the church are welcome to join in the celebrations, making Corpus Christi a significant cultural event in Liechtenstein's calendar.
