The Eels star is charged with three counts of domestic violence against former girlfriend Perina Ting.
His lawyer entered the not guilty plea on his behalf, with Radradra silent throughout the short proceedings.
The Australian and Fijian representative made no comments as he left court.
Radradra was arrested upon returning to Sydney from Fiji late last week, with officers seizing him once he stepped through Customs.
His former partner, Ms Ting, has also applied for an Apprehended Violence Order against the Parramatta winger and claims she was allegedly assaulted on numerous occasions between October 2014 and May 2015.
Radradra must still abide by his bail conditions and have no contact with Ms Ting.
The Eels star will return to court on August 16.
