A tubular threaded joint comprising a first tubular member having a pin and a second tubular member having a box, wherein: the pin is an end portion of the first tubular member and comprises on its radially outward-facing surface a male threaded zone comprising a tapered male thread; the box is an end portion of the second tubular member and comprises on its radially inward-facing surface a female threaded zone comprising a tapered female thread; the male thread and female thread are configured to engage with each other when the joint is in a made-up state; the male thread and female thread are each trapezoidal and comprise a crest (154, 254), a root (158, 258), a load flank (152, 252), and a stabbing flank (156, 256); on both of the male thread and the female thread at least one of the load flank (152, 252) and the stabbing flank (156, 256) is negatively inclined; a first portion of the male thread extending from an end thereof has a first taper relative to a longitudinal axis of the first member; a first portion of the female thread extending from an end thereof has a second taper relative to a longitudinal axis of the second member, the first portion of the male thread and the first portion of the female thread are configured to engage with each other when the joint is in the made-up state; the second taper is different from the first taper such that the threads (150, 250) converge toward an end of the threads in the made-up state; the male thread varies in axial width along its length such that it narrows towards the terminal end of the pin; and the female thread varies in axial width along its length such that it narrows towards the terminal end of the box. the pin is an end portion of the first tubular member and comprises on its radially outward-facing surface a male threaded zone comprising a tapered male thread; the box is an end portion of the second tubular member and comprises on its radially inward-facing surface a female threaded zone comprising a tapered female thread; the male thread and female thread are configured to engage with each other when the joint is in a made-up state; the male thread and female thread are each trapezoidal and comprise a crest (154, 254), a root (158, 258), a load flank (152, 252), and a stabbing flank (156, 256); on both of the male thread and the female thread at least one of the load flank (152, 252) and the stabbing flank (156, 256) is negatively inclined; a first portion of the male thread extending from an end thereof has a first taper relative to a longitudinal axis of the first member; a first portion of the female thread extending from an end thereof has a second taper relative to a longitudinal axis of the second member, the first portion of the male thread and the first portion of the female thread are configured to engage with each other when the joint is in the made-up state; the second taper is different from the first taper such that the threads (150, 250) converge toward an end of the threads in the made-up state; the male thread varies in axial width along its length such that it narrows towards the terminal end of the pin; and the female thread varies in axial width along its length such that it narrows towards the terminal end of the box.
