Leading twist light cone distribution amplitudes (LCDAs) are key ingredients in calculating various hadronic amplitudes using light cone QCD sum rules. This work concentrates on calculating the leading twist LCDAs of p-wave heavy quarkonia. Quark model wave functions for the ground, first, and second excited states of p-wave charmonia and bottomonia have been calculated and are used for calculating the relevant LCDAs and leptonic decay constants.
