The African five-lined skink (Trachylepis quinquetaeniata, formerly Mabuya quinquetaeniata), or rainbow mabuya, is a north-central African species of skink lizard.

T. margaritifera is another closely related skink species that is also called the "rainbow skink" (although it occurs primarily in Eastern Africa); T. margaritifera, overall, possesses more colourful, "rainbow"-like scales (as opposed to the predominantly blue, black and yellowish five-lined skink, T. quinquetaeniata).
