The ITV soap beat Channel 4 shows Hollyoaks and Shameless to the title at the November 19 ceremony.
Corrie star Jane Danson also won the 'Best Performance In A Continuing Drama' award for her role as Leanne Barlow, beating Hollyoaks favourites Emmett Scanlan (Brendan Brady) and Claire Cooper (Jacqui McQueen).
The soap notched up a third victory by bagging the 'Best Script Writer' award, which saw Daran Little take home the trophy for BBC drama The Road To Coronation Street.
The one-off special, which told the story of how Corrie made it to air, was produced to mark the programme's 50th anniversary last year and starred David Dawson and Jessie Wallace.
The Road To Coronation Street previously won big at this year's Royal Television Society Programme Awards and the New York Festivals International Television and Film Awards.
