The 39-year-old actor, best known for his role as Simon Kaminski in the BBC One medical drama, will play a new love rival for Dev Alahan (Jimmy Harkishin) on the soap.
Colquhoun's character Matt Davis is the fiancé of Weatherfield returnee Sunita (Shobna Gulati), who was written out in 2006 after discovering that husband Dev had been unfaithful.
It is thought that Dev will be jealous when he hears about Sunita's wedding plans, leading to a string of heated bust-ups between the businessman and his ex-partner's new flame.
A source told The Sun: "Shobna and Christopher are delighted at the prospect of working together. There's a terrific chemistry between them and they are a perfect match physically and mentally."
Colquhoun will begin filming this week and appear on screen from December.
