The 68-year-old, who plays Jim Branning on the BBC soap, told bosses he wants to be back in Albert Square in the summer.
A show insider told The Sun: "John is doing really well and we're overwhelmed he wants to return. Other people who have suffered serious strokes can be given a boost by watching [him]."
Jim's wife Dot Cotton recorded an audiotape of memories for her husband during a special single-hander earlier this year.
Actress June Brown, who later revealed that she had fought back tears during her monologue, is said to be "thrilled" at his possible return.
However, Bardon's comeback will depend on the progress of the intensive rehabilitation programme he has been undergoing since his stroke.
Brown, 81, said: “He is walking now and can move his arm again. He just needs to work on talking.”
