Christina Yuna Lee was headed home on Sunday, February 13, when a man followed her inside and stabbed her 40 times.
Organizers say Saturday's vigil was to help the community heal and find hope.
It took place at the Sara D. Roosevelt Park basketball court in Chinatown.
People of all faiths and backgrounds were welcomed to join.
The family of Lee is also raising money for charity in her honor.
Relatives set up the GoFundMe for Lee a week after her death, and it has already surpassed $340,000.
