Using the ARGUS detector at the e<sup>+</sup>e<sup>−</sup> storage ring DORIS II at DESY, we have obtained the first evidence for B meson decays into <sub>χc</sub> mesons. The inclusive branching ratio for the decay B → <sub>χc</sub> X was measured to the (1.05±0.35±0.25)% assuming no <sub>χc2</sub> production. In addition, four candidates for the exclusive decay B<sup>±</sup> → <sub>χc1</sub>K<sup>±</sup> have been observed, corresponding to a branching ratio of (0.19 ± 0.13 ± 0.06)%.
