EastEnders, Emmerdale and Hollyoaks have all united in their sadness and shared their condolences via social media.
Corrie announced the death of Tony in a statement: "It is with great sadness that Coronation Street confirms legendary creator and acclaimed writer Tony Warren MBE, passed away peacefully last night surrounded by his loving friends (1 March 2016), aged 79, after a short illness.
"All who worked with Tony throughout his illustrious career had the utmost respect for his achievements and he remained a consultant on the show until the day he died."
As the creator of Britain's longest-running and most successful soap opera, Tony devised the idea for Coronation Street at the age of 24 and continued to write episodes sporadically until the late 1970s.
Soap stars also paid their tribute. Corrie's Kym Marsh called Tony a "true legend", and Emmerdale star Gemma Oaten said he "put the north and soap as we know it on the map".
Meanwhile, EastEnders' Adam Woodyatt called Tony the "original godfather of UK soap".
