  We present a unified parametrization of quark and lepton mixing matrices. By
using some simple relations between the mixing angles of quarks and leptons,
i.e., the quark-lepton complementarity, we parametrize the lepton mixing matrix
with the Wolfenstein parameters $\lambda$ and $A$ of the quark mixing matrix.
It is shown that the Wolfenstein parameter $\lambda$ can measure both the
deviation of the quark mixing matrix from the unit matrix, and the deviation of
the lepton mixing matrix from the exactly bimaximal mixing pattern.
