We derive an analogue of Berry phase associated with inflationary
cosmological perturbations by obtaining the corresponding wavefunction. We have
further shown that cosmological Berry phase can be completely envisioned
through the observable parameters. So one can, in principle, establish a
supplementary probe of inflationary cosmology through the measurement of the
associated Berry phase. Finally, we discuss some possible consequences of this
quantity in inflationary cosmology.
