Using a sample of $31.3 x 10^6 $B\bar{B}$ pairs collected with the Belle
detector at the Y(4S) resonance, we make the first observation of the charged B
meson decay to chi_c0 and a charged kaon. The measured branching fraction is
Br(B+ -> chi_c0 K+)=(6.0^{+2.1}_{-1.8}\pm1.1)x10^{-4}, where the first error is
statistical, and the second is systematic.
