$55,000 ... that's how much it took for the chick from Michael Jackson's "Thriller" music video to call a truce in her war with the MJ estate ... TMZ has learned.
TMZ broke the story ... Ola Ray settled her lawsuit with the estate earlier this year, and now we know what for ... $55,000 to Ola ... and $20,000 to her lawyer.
Ola originally filed the suit against MJ and his production company in May 2009 -- a month before Jackson passed away -- claiming breach of contract. Ola said she was still owed a massive chunk of the "Thriller" profits ... nearly 30 years after it was released.
The director of the music video John Landis -- who filed a similar lawsuit against the estate -- has also settled ... but he wanted in excess of $2 million, so we're guessing he got a little more than Ola.
