The Oscar-winning star, who turned 45 on Thursday, also donated $200,000 to the NAACP Legal Defense Fund, reports people.com.
"Rights don't belong to any one group to give to another. Discrimination and impunity cannot be tolerated, explained away or justified. I hope we can come together as Americans to address the deep structural wrongs in our society," Jolie said.
"I stand with the NAACP Legal Defence Fund in their fight for racial equality, social justice, and their call for urgent legislative reform," she added.
Meanwhile, the actress celebrated her birthday amid lockdown with her six children -- Maddox, 18, Pax, 16, Zahara, 15, Shiloh, 14, and 11-year-old twins Knox and Vivienne.
The actress and activist has been active since the COVID-19 pandemic spread around the world and has donated to different organisations.
Jolie previously donated $1 million to No Kid Hungry, the organisation working to feed children during the COVID-19 pandemic.
"I knew that there were problems in America, that there was poverty, but I could not believe when I realised how many school children in America were dependent on a meal to not go hungry.
