Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon (\Xi_{c}^{o}) using the decay channels (\Xi_{c}^{o}\to \Xi ^{-}\pi ^{+}) and (\Xi_{c}^{o}\to \Omega ^{-}K^{+}). From a combined sample of (110\pm 17) events we find (\tau (\Xi_{c}^{o}) =~118^{+ 14}_{- 12} \pm5) fs, where the first and second errors are statistical and systematic, respectively.
