Marchantiales is an order of thallose liverworts that includes species like Lunularia cruciata, a common and often troubleseome weed in moist, temperate gardens and greenhouses.

As in other lower plants, the gametophyte generation is dominant, with the sporophyte existing as a short-lived part of the life cycle, dependent upon the gametophyte.

The genus Marchantia is often used to typify the order, although there are also many species of Asterella and species of the genus Riccia are more numerous.
