We present a search for a light CP-odd Higgs boson (A0) in Upsilon(1S) -> gamma A0, A0 -> ccbar decays. The Upsilon(1S) mesons are selected via the dipion transition Upsilon(2S) -> pi+pi- Upsilon(1S), and the A0 -> ccbar final state is tagged through the reconstruction of various D(*) mesons. No significant signal is observed, and limits on the product branching fraction B(Upsilon(1S) -> gamma A0)xB(A0 -> ccbar) are set at the level of 7x10-5 - 2x10-3 for A0 masses between 4.0 GeV and 9.25 GeV.
