We generalize Grothendieck's residues Res\fracψs to virtual cases, namely cases when the zero loci of the section s has dimension larger than the expected dimension(zero). We also provide an exponential type integral formalism for the virtual residue, which can be viewed as an analogue of the Mathai-Quillen formalism for localized Euler classes.
