We report the first observation of [chi][sub](c2) production in B-meson decays. We find an inclusive B [to] [chi][sub](c2)X branching fraction of (((1.80[sub]-0.28)[sup]+ 0.23) [plus minus] 0.26) x 10[sup]-3. The data set, collected with the Belle detector at the KEKB e[sup]+ e[sup]- collider, consists of 31.9 x 10[sup]6 BB[bar] events. We also present branching fractions and momentum spectra for both [chi][sub](c1) and [chi][sub](c2) production
