We study Lambda_b --> Lambda pi pi. The branching fraction is predicted to be
about 4.38 x 10^{-6}%. Within the standard model, we compute T-odd triple
product asymmetries to be about 1.4, 4.3, 6.5 and 7.2% respectively due to
s_{Lambda_b}(s_Lambda) . (p_Lambda x p_pi) and p_Lambda (p_pi) . (s_Lambda x
s_{Lambda_b}).
