Haque, who played Rovers Return barmaid Poppy Morales, passed away in her sleep at a London hospital earlier today (January 17).
A Coronation Street spokesperson told Digital Spy: "We are saddened to hear the terrible news of Sophiya's death. She was a vibrant and beautiful actress who was a pleasure to have around during her time on Coronation Street. Our thoughts are with her family and friends at this very sad time."
The Evening Standard reports that Haque had been undergoing tests after being diagnosed with cancer.
She reportedly developed a clot on her lungs and passed away in the early hours of this morning.
Haque's agent Stuart Piper told The Stage: "Sophiya was one of the most inspirational people I ever met. She was the kind of person you always want to spend time with - full of light, warmth, compassion, care and with an infectiously wicked sense of humour, and my co-agent Olivier Thomson and I loved every minute of working with her."
The actress appeared as Coronation Street's Poppy between December 2008 and June 2009. Poppy was brought into The Rovers as the pub's 51st barmaid, before landing the position of assistant manager.
During her time on the cobbles, Poppy caused a stir by sacking Betty Williams from her bar job - but was later kicked out herself when she got on the wrong side of Steve and Becky McDonald.
Haque had been appearing in a West End production of Privates on Parade before she fell ill just prior to Christmas.
She had also starred in other West End shows including Bombay Dreams.
