The discovery of a light, singlet-like pseudoscalar Higgs boson, A1, of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) could provide a hallmark signature of non-minimal supersymmetry. We review here the potential of the LHC to probe such a light A1 in the decays of one of the heavier scalar Higgs bosons of the NMSSM. We find the production of pairs of the A1, with a mass below 60 GeV or so, via decays of the two lightest scalar states to be especially promising, for an integrated luminosity as low as 30/fb. For heavier masses, the decay of the heaviest scalar into a Z boson and an A1 could lead to its detection at the LHC.
