Forza Nuova (New Force) said the list would name managers of hotels that are hosting migrants in the Emilia-Romagna region, La Repubblica reported.
With immigration centres over capacity across Italy, local authorities pay hoteliers €30 a day to host migrants.
But the move puts “the health and the security of the population” at risk, Forza Nuova’s Emilia-Romagna branch claimed.
“The use that these hotels unscrupulously make of immigration is deplorable and humiliating.
“Stop immigration and fight for the total repatriation of all the immigrants in the country, it’s no longer a right but a must,” the party said.
The extreme-right group has long been vocal about its anti-immigration views, recently carrying out controversial stunts in Italy.
Last year, the party hung nooses around a town ahead of a visit by Cecile Kyenge, then integration minister, followed weeks later by bloodied mannequins targeting the minister.
More recently, members of Forza Nuova marched on a swimming pool in north-east Italy, to protest against a women and children swim slot aimed at integrating Muslims.
While the party is strongly anti-foreigner in many respects, it has kindled relationships with fellow extreme right groups across Europe. Its international partners include Nordic Youth (Nordisk Ungdom), a Swedish extreme-right youth movement, and Flemish nationalist group Outpost (Voorpost).
