A novel physical concept "optical instanton" is presented, which exhibits a particular quasi-particle form of spatiotemporally localized light field in an intensity-dependent nonlinear medium. The physical relevance of the ultimate localization to an ultrafast nonlinear coherent process is discusseed.
