A ratchet pipe wrench includes a C-shaped head composed of two jaws and a ratchet mechanism is received in the head so as to engage with a C-shaped engaging member which is rotatably engaged with the space between the two jaws of the head. The C-shaped engaging member has a polygonal inner periphery so as to engage with an object such as a nut and a toothed outer periphery which is engaged with the ratchet mechanism. The tool can reciprocatingly rotate the object without removing the tool from the object.
