The message to her fans, which began with "Happy Thanksgiving", followed with her mentioning the trending hashtag #me too.
The #metoo hashtag is apart of a trending topic, where women who claim to have been sexually assaulted come forward and tell their stories.
"I am grateful today, to be alive, for all those I love, and for all those who have the courage to stand up for others," the post read.
"I said I was angry recently, and I have a few reasons, #metoo, in case you couldn’t tell by the look on my face."
Thurman ended the post saying she doesn't wish Weinstein a happy Thanksgiving.
"I feel it’s important to take your time, be fair, be exact, so... Happy Thanksgiving Everyone! (Except you Harvey, and all your wicked conspirators - I’m glad it’s going slowly - you don’t deserve a bullet) -stay tuned."
Many women have claimed they have been sexually assaulted by Weinstein.
Celebrities such as Angelina Jolie, Gwenyth Paltrow, Cara Delvinge and Kate Beckinsale are a few among many.
Thurman used a photo of herself in Kill Bill: Volume 2 with her message, a movie which Weinstein was an executive producer of.
The photo is a scene in which Uma's character, Beatrix Kiddo, is seeking revenge.
