A golf swing analysis apparatus for analyzing a swing action of a golf club is provided. The golf swing analysis apparatus comprises an acquisition unit configured to acquire a measurement value obtained by measuring the swing action using a measurement device; a grip behavior derivation unit configured to derive a behavior of a grip of the golf club that occurs during the swing action, based on the measurement value; and a shoulder behavior derivation unit configured to derive a behavior of a pseudo shoulder of a golfer that occurs during the swing action, based on the behavior of the grip.
