Susan Barlow (also Baldwin) is a fictional character from the British ITV soap opera Coronation Street.

The fourth actress to play the role was Joanna Foster, who appeared in eight episodes in 2001 until the character was killed off.

Katie Heanue played Susan as a baby and young child from 1965 until 1970 when Heannau and her family moved away from the Manchester area.

After a thirteen-year absence, Susan returned for a final time in early 2001, now played by Joanna Foster, which saw the character get killed off after introducing her secret son Adam.

[3] In January 2001, the character returned to Coronation Street with actress Joanna Foster taking over the role.

[4] Susan comes back to Weatherfield to introduce her son, Adam (Iain de Caestecker) to his grandfather, Ken (William Roache).

[5] Rick Fulton of the Daily Record said Ken is "amazed, but also devastated" that Susan kept his grandson a secret for so long.

The Barlows had many friends and could easily find babysitters, allowing Valerie to attend evening classes in Sociology.

In November 1965, Ken was looking after the twins but when he visited The Rovers Return briefly, a piece of coal fell from the fire and filled the house with smoke.

Valerie left him briefly and took the twins to Glasgow but returned when he convinced her that he would be a more devoted husband and father from then on.

In 1968, the Mission of Glad Tidings and Elliston's Raincoat Factory across the Street were torn down to make way for a block of maisonettes.

Later in the year, Peter and Susan were sent to live in Scotland with their maternal grandparents after Ken struggled to make suitable childcare arrangements and continue to work as a teacher.

Mike branded her a killer and a murdering bitch and she left him and moved to Newcastle after just a year of marriage in November 1987.

[7] He commented on her 2001 recast saying "I don't know why either of them believed a word she said, since Susan had been blonde and blue-eyed, and this impostor had black hair and brown eyes.

[7] Kerry Barrett from Entertainment Daily wrote that Susan's life was "full of drama" and called the character a "tragic mum".

[2] In 2017, a storyline revisited the character when it was revealed that Billy Mayhew (Daniel Brocklebank) was involved in her death in his "dark past".
