"We have read about it in the press, but don't know anything else," said a spokesperson for Golden Dawn of a Spanish party using the same name, symbols and ideology.
The spokesperson also denied any contact with the Spanish party which registered with Spain's interior ministry on October 27th.
Spain's version of Golden Dawn describes itself as being dedicated to "the defence of the identity, roots, culture, values and tradition of the people of Spain and Europe", Spain's El Diario reported.
But little else is known of the party with an Alicante address.
A tight-lipped party president Antonio Vicedo, formerly with Spain's own far-right group National Alliance, said the party would "within a month, or within a month and a half, make officially launch itself, inviting media outlets".
Asked if he had had any contact with Greece's own Golden Dawn said details would be released in due course. "We can't give more information right now."
Greece's Golden Dawn party is openly racist and nationalist, although it denies being a neo-Nazi party. Fuelled by a wave of anti-austerity feeling it won seven percent of the popular vote in the 2012 Greek national elections, gaining 21 seats in the national parliament as a result.
It also picked up just under ten percent of the vote in European Union elections in May, the third highest of any Greek party.
However, the party's leader Nikos Michaloliakos is now in prison facing charges of acting as the head of a criminal group.
Spain's own economic crisis has failed to lead to a rise in popularity of right-wing groups. By contrast, the radical left-wing group Podemos has continued to climb in the polls, threatening the prospects of Spain's two largest parties as they gear up for general elections in 2015..
