  In this talk I consider the current status of $B \rightarrow D^{(*)} \tau
\nu$ decays in the context of two-Higgs-doublet models. The BaBar collaboration
has reported an excess in semileptonic $b \rightarrow c \tau \nu$ transitions
that has gathered recent interest as a possible signature of new physics. The
sensitivity of these decays to tree-level charged Higgs boson contributions is
discussed, taking into account the constraints from other semileptonic and
leptonic meson decays in which the charged Higgs would enter at the same level.
