  The first observation of \chi_cJ (J=0,1,2) decays to Lambda Lambda-bar is
reported using \psi(2S) data collected with the BESII detector at the BEPC. The
branching ratios are determined to be BR(\chi_c0 \to Lambda Lambda-bar) =
(4.7^{+1.3}_{-1.2} \pm 1.0)\times 10^{-4}, BR(\chi_c1 \to Lambda Lambda-bar) =
(2.6^{+1.0}_{-0.9} \pm 0.6)\times 10^{-4} and BR(\chi_c2 \to Lambda Lambda-bar)
= (3.3^{+1.5}_{-1.3} \pm 0.7)\times 10^{-4}. Results are compared with model
predictions.
