PROBLEM TO BE SOLVED: To provide a pile driving method for driving a pile into a subaqueous bottom in a manner improving construction accuracy and ensuring the quality of the pile, and to provide a pile driving apparatus. SOLUTION: According to the pile driving method the pile 10 is driven into a sea bottom 90 by using a hull 2. Specifically the pile 10 is supported by a pile holder 4 arranged on the hull 2, and when the pile 10 kept in a supported state is driven into the sea bottom 90, a relative location of a leader portion 5 of the pile holder 4 with respect to the hull 2 is moved according to fluctuation of the water level, to thereby maintain the constant location of the pile 10. Therefore the hull 2 need not be moved according to the fluctuation of the water level, which enables holding of the pile 10 at a correct driving location, to thereby improve the pile driving accuracy.
