The former Holby City actor will play the role of Danny Stratton, who meets Becky (Katherine Kelly) later this year in the build-up to her departure from the soap.
Danny arrives on the scene at an ideal time for Becky as she is trying to move on from her failed marriage to Steve McDonald (Simon Gregson), who is now in a relationship with Tracy Barlow (Kate Ford).
Coronation Street's producer Phil Collinson told itv.com: "I'm delighted to be welcoming Jeremy to the cast. Danny will be integral to the unmissable final chapter of the Steve/Becky/Tracy love triangle.
"It's thrilling that such a key character will be in the hands of such a fine actor."
As well as playing Alex Adams on Holby City, Sheffield has appeared in a number of other TV shows and films, including Murder in Suburbia, Creep and The Wedding Date. He also competed in the 2010 series of ITV1's Dancing On Ice.
Becky's final Coronation Street scenes will air in early 2012.
