Eulamprus is a genus of lizards, commonly known as water skinks, in the subfamily Sphenomorphinae of the family Scincidae.

The genus Eulamprus belongs to a clade in the Sphenomorphus group that contains other genera such as Ctenotus and Anomalopus.

The molecular phylogenetic studies of O'Connor and Moritz (2003) and Skinner et al. (2013) found that species assigned to Eulamprus comprised four independent lineages within the Australian Sphenomorphus group and did not form a clade.

The genus Eulamprus was restricted to the water skinks, with other species assigned to Concinnia (including species formerly in the monotypic genera Gnypetoscincus and Nangura), Silvascincus and Tumbunascincus.
