(57) An object of the present disclosure is to provide a threaded connection for steel pipe with large diameter that can exhibit high torque resistance and high sealability and, at the same time, provide a shear resistance that suits the size of the steel pipe to be connected. The threaded connection 1 for steel pipe includes a tubular pin 10 provided on a tip of a steel pipe 2 with large diameter, and a tubular box 20 adapted to be made up on the pin 10 as the pin 10 is screwed in. The pin 10 includes a male threadform 11 made with a taper thread. The box 20 includes a female threadform 21 made with a taper thread. Each of the threadforms 11 and 21 is a wedge threads and has a dovetail-shaped cross section. The male threadform 11 is designed to satisfies the following expressions (1) and (2) such that the width of the thread in an end region of the male threadform closer to the tip is set to a size corresponding to the size of the pipe body of the steel pipe 2.
