Answer: Lyanna Stark

In the season 6 finale ("The Winds of Winter") the popular fan theory named R+L=J was finally confirmed. During one of Bran's visions, we see the Tower of Joy and the birth of Jon. Lyanna made Ned promise her to take care of her son. In order to protect the boy, Ned raised him in Winterfell as his bastard son, avoiding talking about his mother and frequently saying that it was a prostitute.
It is proven that Lyanna is Jon's mother during this episode, but the confirmation of Rhaegar as Jon's father was later announced by HBO itself.
