  The most recent b-physics results from the OPAL experiment at LEP are
reviewed. A measurement of semileptonic B meson decays to narrow
orbitally-excited charm mesons is presented first, followed by a study of charm
production in b-hadron decays. Here, B refers to B+ and B0 mesons and their
charge conjugates, and b-hadron refers to the admixture of hadrons containing a
b quark produced in electron-positron annihilations at \sqrt{s}= m_Z.
