L.A. Lakers star Devin Ebanks isn't out of the woods yet ... despite being cleared in a rape investigation last year -- because the woman who accused him of sexual assault has now filed a civil lawsuit.

The woman filed the lawsuit anonymously in L.A. County Superior Court because of an elleged incident that took place when the baller took her home from a nightclub in September 2011.

The L.A. County D.A. refused to file charges against Ebanks due to lack of evidence.

Now, the woman's hoping to recover monetary damages in civil court -- suing Ebanks for sexual assault and battery, defamation, and intentional infliction of emotional distress.

She's suing for unspecified damages.
