"On Monday, following the Deputy Prime Minister's statement regarding his citizenship, I sought advice of the UK Home Office of my citizenship status," she said.
Ms Nash was then advised she is a British citizen by descent from her Scottish father.
She met with Prime Minister Malcolm Turnbull on Thursday and says she will refer herself to the High Court but won't stand aside as deputy leader.
Ms Nash is the latest in a string of Australian MPs who have been found to be dual citizens.
The announcement came minutes before the Senate adjourned for two weeks.
