We present recent results on B-_c meson from the Tevatron.  The
B-_c meson has been observed in semileptonic decays, B-_c --> J/psi l- nu
X, both by CDF and D0 experiments at a significance larger than 5 sigma.
The D0 experiment has used the candidates in B-_c --> J/psi mu- nu X decay
to extract the mass and lifetime of B-_c meson.  The CDF experiment has
used both electron and muon channel candidates in B-_c --> J/psi l- nu X
decays to measure the relative production times branching ratio with respect
to B- --> J/psi K- decay and also measured the lifetime of B-_c meson in
electron channel as tau(B-_c) = 0.463+0.073_-0.065 +/- 0.036 ps.  The CDF
experiment has also observed B-_c --> J/psi pi+- decay with a significance
exceeding 6.5 sigma and has measured the mass of B-_c meson as M(B-_c) =
6276.5 +/- 4.0 +/- 2.7 MeV/c2.
