We report the first measurements of the doubly charmed baryonic B decays B → Λ^+_c Λ^-_c K. The B+ → Λ^+_c Λ^-_c K+ decay is observed with a branching fraction of (6.5^{+1.0}_{-0.9} ±1.1±3.4)x10^{-4} and a statistical significance of 15.4σ. The B^0 → Λ^+_c Λ^-_c K^0 decay is observed with a branching fraction of (7.9^{+2.9}_{-2.3}±1.2±4.1)x10^{-4} and a statistical significance of 6.6σ. The branching fraction errors are statistical, systematic, and the error resulting from the uncertainty of the Λ^+_c →pK^-π^+ decay branching fraction. The analysis is based on 357 fb^{-1} of data accumulated at the Ύ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider.
