Labná is a ruined ceremonial center of the Maya civilization in the state of Yucatán, Mexico.

Labná is in the southwest of the state, south of Uxmal, at 20.09.6 north, 89.35 west.

The site is small and quiet. There is a large two-story palace, (El Palacio). With its 120 meters it's one of the longest buildings in the Puuc Hills. From the palace a sacbe , a ceremonial road, runs to an elaborately decorated gateway arch (El Arco). This structure is 3 meters wide and 6 meters high. The reliefs are in good shape. Next to the gateway stands El Mirador, which is a temple built on a pyramid.

The architecture of the buildings is in the Puuc style, and makes extensive use of well-cut stone forming patterns and depictions, including masks of the long-nosed rain-god Chac.

The site was built in the late and terminal classic period. A date corresponding to 862 is inscribed in the palace.

The first written report of Labná was by John Lloyd Stephens who visited it with artist Frederick Catherwood in 1842.

The site is open for tourist visits.
