Saltacionizam (od lat. saltus: skok), u biologiji iznenadna promjena od jedne do druge generacije koja je velika, ili veoma velika, u usporedbi s običnom varijacijom nekog organizma. Termin se rabi za nestupnjevite promjene (navlastito u jednokoračnoj specijaciji) koje su atipične ili krše gradualizam obuhvaćen modernom evolucijskom teorijom.
