Las Posadas is the Mexican Christmas tradition reenacting Mary and Joseph’s search for lodging.
The name comes from the Spanish word posada, meaning “inn” or “lodging.” During the celebration, participants form processions and carry images of Mary and Joseph, often stopping at homes while singing a traditional exchange of verses. The group asks for shelter, and the hosts initially refuse before finally welcoming the travelers inside.
Las Posadas traditionally takes place over nine nights, from December 16 through December 24. The nine-day period is commonly associated with the nine months of Mary’s pregnancy, although the observance also serves as a devotional preparation for Christmas. Once admitted, participants gather for prayers, food, music, and a piñata, especially in celebrations involving children.
The custom developed in Mexico during the colonial period and was promoted by Catholic missionaries as a way to teach the Nativity story. It is sometimes confused with El Nacimiento, which means a nativity scene, or Los Reyes Magos, the Three Wise Men. Those are related Christmas elements, but neither names this lodging reenactment.
