Tietea was a genus of marattialean tree ferns from the Late Carboniferous to the Permian. The genus has been placed in a number of families, including Psaroniaceae. The first described species was Tietea singularis, which grew up to 12 metres (39 ft) in height. It is estimated to represent close to 90% of some fossil assemblages in Brazil. Tietea derbyi was described in 1992, but its validity has been questioned as it could be a laterally flattened specimen of T. singularis.
