A tieback connector for attaching a riser to a subsea production assembly is provided. The tieback connector includes a main body adapted to be coupled to the subsea production assembly having a central passageway sufficiently large to pass an end of the riser string therein and a connector positioner coupled to the main body, which is adapted to secure the tieback connector around a circumferential surface of a wellhead of the subsea production assembly. The tieback connector further comprises an aligning extension portion defined by a funnel-shaped tip, which aids alignment of the riser terminus during landing of the riser string onto the wellhead. The tieback connector secures the riser to the wellhead.
