The pure rotational spectrum of CrS has been measured in the ground X^{5}Π_r state using gas-phase direct absorption methods in the frequency range of 280-405 GHz. The molecule was created by the reaction of chromium vapor, sublimed in a Broida oven, with hydrogen sulfide gas. All five spin components were observed in eleven rotational transitions, and lambda-doubling splitting were resolved in the Ω = 0, 1 and 2 ladders. The data were fit with a Hund's case(a) Hamiltonian and rotational, spin-orbit, spin-spin, and lambda-doubling constants have been established. A bond length of 2.0781 Å was derived from the data. Using the lambda-doubling parameters, the energy difference between the ground X^{5}Π and excited ^{5}Σ state was estimated to be 1400 cm ^{-1}.
