Islamic Iran Solidarity Party (Persian: حزب همبستگی ایران اسلامی; Hezb-e Hambastegi-e Iran-e Eslami) is an Iranian reformist political party founded in 1998, by 10 members of Parliament of Iran.

The party is a member of Council for Coordinating the Reforms Front[4] and publishes the newspaper Hambastegi.

Ali Asghar Ahmadi is the general secretary, an office previously held by Ebrahim Asgharzadeh and Mohamadreza Raahchamani.
