PROBLEM TO BE SOLVED: To provide a steel pipe sheet pile joint and a joint structure of a steel pipe sheet pile which ensure the positioning accuracy of the steel pipe sheet pile, which have proper workability associated with excavation and washing of sediment in a joint part, and mortar filling, which surely enhance joint shearing strength in a pipe axis direction and which can resist an axial force in a cross section, , and a steel pipe sheet pile foundation. SOLUTION: The steel pipe sheet pile joints are connected together by a female joint 13 and a male joint 17. In the female joint 13, a pair of L-shaped steel materials 10 is provided at a predetermined interval in the axial direction of an outer shape of a steel-pipe-sheet-pile main pipe 3; an arm part 11 of each L-shaped steel material 10 is arranged inward; and a leg part 12 of each L-shaped steel material 10 is fixed. In the male joint 17, a pair of L-shaped steel materials 14 is provided at a predetermined interval in the axial direction of the outer shape of the steel-pipe-sheet-pile main pipe 3; an arm part 15 of each L-shaped steel material 14 is arranged outward; and a leg part 16 of each L-shaped steel material 14 is fixed. A plurality of rod-like steel materials with protrusions are arranged on the outer peripheral surface of the main pipe, which is sandwiched between each L-shaped steel materials of the female joint and that of the male joint, at intervals at least three times longer than a diameter of the rod-like steel material with the protrusion in the direction of the outer periphery of the steel pipe.
