Derrick Rose Rape Accuser Demanding $21.5 MILLION

The accuser in the Derrick Rose rape lawsuit has finally named her price -- $21.5 MILLION -- this according to court docs obtained by TMZ Sports.

We broke the story ... a woman is suing the Chicago Bulls star claiming he and 2 friends broke into her L.A. apartment and gang raped her back in 2013.

Rose later acknowledged the group sex, but claims it was consensual, and says he engaged in the group sex with the accuser on several previous occasions.

Now, the case is moving forward and the accuser has set her price tag -- $6 million in compensatory damages and $15.5 in punitive.

FYI -- Rose signed a 5 year contract worth $94.3 million back in 2011.
