To provide a pipe joint and a pipe joint connection system that prevent trouble caused by proceeding the connection between a first joint and a second joint in a state that the first joint and the second joint are displaced from each other.

The pipe joint connection system 90 includes a pipe joint 10 and a moving device 91. The pipe joint has: a male member 20 having male joints 21; a female member 30 having female joints 31 connected with the male joints 21 by inserting the male joints 21 thereinto; each guide pin 23 provided on the male member 20; and each guide member 33 provided on the female member 30 and having a guide hole 34 into which the guide pin 23 is insertable. The moving device is configured to move the male member 20. A piezoelectric element 60 is arranged at the tip 23a of the guide pin 23. The moving device 91 includes a control part 93 which receives a voltage signal sent from the piezoelectric element 60 and stops the movement of the male member 20 toward the female member 30.
