The invention relates to the technical field of steel pipe detection, and discloses a positioning device for steel pipe surface straightness detection, which comprises a hollow plate, rollers I, L-shaped rods, a moving plate, a top plate, rollers II, a U-shaped frame, a round rod and a dial indicator, the two rollers I are symmetrically mounted at the top end of the hollow plate, and the two L-shaped rods are symmetrically mounted at the left and right ends of the hollow plate in a sliding manner; and a U-shaped frame is fixedly installed in the middle of the top end of the top plate, a dial indicator is fixedly installed at the top end of the interior of the U-shaped frame, and a round rod is slidably installed in the middle of the top end of the top plate. A seamless steel pipe extrudes a third roller to drive a round rod to move so as to measure the straightness of the steel pipe, meanwhile, a driving motor works to drive a two-way screw to rotate so as to change the positions of two second rollers, and th
