The '''Euclidean mapping''' is a special case of [[affine mapping]] that, besides collinearity and ratios of distances, keeps also ''distances'' and ''angles''. Because of this, a Euclidean mapping is also called a ''rigid motion''.

Euclidean mappings are of three types:
* translations
* rotations
* reflections.

A special case of Euclidean mapping is a [[symmetry operation]].
