Malala Yousafza, 14 years old, was severely injured last week after being targeted by the Taliban in Pakistan for speaking out in favour of women's education.
Yousafza was flown to the UK for medical care in the wake of the attack. She is expected to survive, but will need extensive surgery to repair her skull.
Jolie's Education Partnership for Children of Conflict has now donated $50,000 to Tina Brown's Women in the World Foundation as part of a fundraising drive for Yousafza's cause.
Brown and Jolie have also co-written an open letter calling for women around the world to demand education rights.

Their joint statement reads: "We are sure you have been shaken by the news that last week, 14-year old Malala Yousafzai was shot in the head by the Taliban as she left school in the Swat Valley in Pakistan. Her crime was promoting girls' education in Pakistan and publishing a blog about life under the Taliban. She remains unconscious, and has been flown from Pakistan to the United Kingdom to receive specialist treatment
"As a response to Malala's bravery, girls across Pakistan, Afghanistan and the world are standing up and saying, 'I am Malal'" - and this is our opportunity to show the same solidarity. Tina Brown and Angelina Jolie."
Donations are being accepted on the Women in the World Foundation website.
A portion of the funds raised will create a Women of Impact Award for Girls' Education in honour of Yousafza.
