  A precise determination of the charm-strange baryon Cascade(c)+ lifetime is
presented. The data were accumulated by the Fermilab high-energy
photoproduction experiment FOCUS. The measurement is made with 300 Cascade(c)+
--> Cascade- pi+ pi+ decays, 130 Cascade(c)+ --> Sigma+ K- pi+ decays, 45
Cascade(c)+ --> p K- pi+ decays and 58 Cascade(c)+ --> Lambda K- pi+ pi+
decays. The Cascade(c)+ lifetime is measured to be 0.439+/-0.022+/-0.009 ps.
