We present a systematic study of twist-3 light-cone distribution amplitudes of K* and phi mesons in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non-perturbative input parameters are estimated from QCD sum rules. As a by-product, we update the parameters describing the twist-3 distribution amplitudes of the rho meson. We also review and update predictions for the twist-2 distribution amplitudes of rho, K* and phi.
