We have searched for CP violation in the decays D0→KS0P0 where P0 denotes a neutral pseudoscalar meson that is either a π0, η, or η^′ using KEKB asymmetric-energy e⁺e^- collision data corresponding to an integrated luminosity of 791fb^-1 collected with the Belle detector. No evidence of significant CP violation is observed. We report the most precise CP asymmetry measurement in the decay D0→KS0π0 to date: ACPD0→KS0π0=(-0.28±0.19±0.10)%. We also report the first measurements of CP asymmetries in the decays D0→KS0η and D0→KS0η^′: ACPD0→KS0η= (+0.54±0.51±0.16)% and ACPD0→KS0η^′=(+0. 98±0.67±0.14)%, respectively.
