Hannah Bladon who was in her early 20s died soon after being rushed to hospital.
She was attacked as she travelled on the light rail near Jerusalem's Old City, which was packed with Christians celebrating Good Friday and Jews celebrating Passover.
Israel's Shin Bet security agency identified the assailant as a 57-year-old Palestinian man and said that he suffered with mental health problems.
He added that he had previously tried to take his own life.
In a statement, Shin Bet said "This is one of many instances where a Palestinian suffering personal strife chooses to carry out an attack in order to find release for his problem."
According to media reports, the attacker stabbed the woman multiple times and was armed with a kitchen knife.
Footage from the scene showed officers grabbing the assailant and forcing him to the ground while passengers attempted to get off the train.
Police spokesman Micky Rosenfeld said the suspect is being questioned "as to his motives...and if he planned the attack on his own".
