''Almasaurus'' is an extinct genus of trematosaurian temnospondyl within the family Latiscopidae. It is known from several skulls and some postcranial material found from the Argana Formation in Morocco, which dates back to the Early Triassic. When it was first named in 1972, ''Almasaurus'' was placed within its own superfamily, the Almasauroidea. Although the related latiscopid ''Latiscopus disjunctus'' possesses exoccipitals that are underplated (a feature that suggests that it is a member of the family Trematosauridae) ''Almasaurus'' is not considered to be a trematosaurid because it lacks such underplating.〔 ''Almasaurus'' was considered to be a capitosaurian by Warren & Black (1985) because it shared several characters with the group, including a deeply notched squamosal and a lacrimal flexure, while supposedly exhibiting none of the characters associated with trematosaurians.〔 However, more recent studies have concluded that ''Almasaurus'' is either a temnospondyl more basal than the clade formed from the dichotomy between Capitosauria and Trematosauria or that the genus is closely related to the trematosaurian family Metoposauridae, perhaps being a sister taxon of it. A temnospondyl genus described in 2000, ''Rileymillerus'', is thought to be closely related to ''Almasaurus''.
