The Lambda_c baryon mass is measured using 
Lambda_c to Lambda  K^0_S K^+ and 
Lambda_c to Sigma^0 K^0_S K^+ decays reconstructed in 
232 fb^-1 of data collected with the BaBar detector at the PEP-II
asymmetric-energy e^+e^- storage ring. The Lambda_c mass is measured
to be 2286.46 +- 0.14 MeV/c^2.  The dominant systematic uncertainties
arise from the amount of material in the tracking volume and from the
magnetic field strength.
