This thesis describes a measurement of the lifetime of the Bc meson in an exclusive decay channel Bc to J/psi pi. The measurement uses a data sample with an integrated luminosity of 6.7 fb$^{-1}$ collected at CDF. This is the first measurement of the Bc meson lifetime in a hadronic channel and the measured lifetime, $\tau = 0.449~^{+0.054}_{-0.048}(stat.)~\pm~0.019(syst.)$~ps, is in good agreement with previous results obtained from semileptonic decay channel and confirms previous measurements and theoretical predictions.
