A medical connector according to the present disclosure includes: a first connection section； a second connection section； and a rotation control section that controls relative rotation of the first connection section and the second connection section in a connection state. The second connection section includes a wall face that abuts on the first connection section to restrict the first connection section from moving in a direction to be separated from the second connection section. The rotation control section allows the second connection section to rotate relative to the first connection section in a first circumferential direction about the axis as a central axis and restricts the second connection section from rotating relative to the first connection section in a second circumferential direction opposite to the first circumferential direction, in a state where the first connection section abuts on the wall face. The first connection section is connectable to a different medical device using a rotating operation in the second circumferential direction and is disconnectable from the different medical device using a rotating operation in the first circumferential direction.
