To stably connect pipes arranged along the inner peripheral surfaces of steel pipe piles at a connection part connecting the steel pipe piles in an axial direction using an inner fitting member and an outer fitting member.SOLUTION: A connection structure of steel pipe piles is provided that includes: an inner fitting member connected to an end part in the axial direction of a first pile body; an outer fitting member connected to an end part in the axial direction of a second pile body; a first pipe connected to the inner peripheral surface of the first pile body; and a second pipe connected to the inner peripheral surface of the second pile body. The inner fitting member includes a first fitting part that fits inside the outer fitting member and a through hole to communicate the inside of the inner fitting member with the outside of the first fitting part. The outer fitting member includes a second fitting part that fits outside the inner fitting member. The first pipe and the second pipe are connected through the through hole and a passage formed between the first fitting part and the second fitting part.
