Alex Da Silva -- a former choreographer for "So You Think You Can Dance" -- has just pled not guilty to raping several women between 2002 and 2009.
Da Silva -- who appeared in L.A. County Superior Court this morning -- denied all eight felony charges against him ... including four counts of forcible rape, two counts of assault with intent to
commit rape and two counts of sexual penetration by a foreign object.
Da Silva's alleged victims were all dancers who say they met him through his dance intstruction classes.
Da Silva has been in custody since his arrest back on August 18.
He's due back in court on June 11.
