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; and 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; characterised in that: the female thread comprises a distal end nearest the terminal end of the box and a proximal end opposite the distal end; the female thread comprises a complete portion and an incomplete portion, the incomplete portion being at the proximal end of the female thread; and the crest of the incomplete portion of the female thread defines a cylindrical surface, or a conical surface, or the crest of the incomplete portion of the female thread defines a cylindrical surface extending to a conical surface, with the conical surface nearest the proximal end of the female thread; or the male thread comprises a distal end nearest the terminal end of the pin and a proximal end opposite the distal end; the male thread comprises a complete portion and an incomplete portion, the incomplete portion being at the proximal end of the male thread; and the crest of the incomplete portion of the male thread defines a cylindrical surface, or a conical surface, or the crest of the incomplete portion of the male thread defines a cylindrical surface extending to a conical surface, with the conical surface nearest the proximal end of the male thread. 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;

or the male thread comprises a distal end nearest the terminal end of the pin and a proximal end opposite the distal end; the male thread comprises a complete portion and an incomplete portion, the incomplete portion being at the proximal end of the male thread; and the crest of the incomplete portion of the male thread defines a cylindrical surface, or a conical surface, or the crest of the incomplete portion of the male thread defines a cylindrical surface extending to a conical surface, with the conical surface nearest the proximal end of the male thread.
