Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

Retardation may refer to:

Medicine and biology

  • Mental retardation, a disorder characterized by significantly impaired cognitive functioning and deficits in adaptive behaviors
  • Psychomotor retardation, a slowing-down of thought and a reduction of physical movements in an individual
  • Neoteny, retention by adults of traits previously seen only in the young

Physics and engineering

  • Retardation factor, in chromatography, the fraction of an analyte in the mobile phase of a chromatographic system
  • Retarded potential, in electrodynamics, electromagnetic potentials generated by time-varying electric current or charge distributions in the past
  • Retarded time, time when an electromagnetic field began to propagate from a point in a charge distribution to an observer
