A stress joint for a subsea riser has a reduced diameter intermediate section to reduce bending stresses on the connection between the stress joint and the riser as well as the subsea equipment. The stress joint having a riser joint with a threaded upper end for connection to a riser string. Attached to a lower end of the riser joint is an upper transition section that tapers from the diameter of the riser joint to a reduced diameter. An intermediate section below the upper transition section has a reduced outer diameter. A lower transition section connects the lower end of the intermediate section to the subsea equipment. The lower transition section is tapered from a reduced diameter to a larger diameter to ensure a firm connection with the subsea equipment.
