Abstract: We present several examples in noncommutative quantum cosmology, using the WKB-type approximation with a deformation on the minisuperspace variables. This procedure gives a straightforward algorithm to incorporate noncommutativity to cosmology and inflation.

Keywords: noncommutative cosmology, quantum cosmology, quasiclassical approximation.
