The {{nihongo|Aikokusha|愛国社||"Society of Patriots"}} was a political party in the early Meiji-period Japan from 1875 to 1880.

The Aikokusha was formed in February 1875 by Itagaki Taisuke, as part a liberal political federation to associate his Risshisha with the Freedom and People's Rights Movement. It was disbanded the same year, when Ōkubo Toshimichi promised Itagaki that the government would draft a constitution.

When no constitution had appeared by September 1878, Itagaki revived the Aikokusha and renamed it the League for the Establishment of a National Assembly. Its primary purpose was to petition the government to establish a national assembly. It was renamed Liberal Party, which Itagaki founded in October 1881.{{cite book|title=Introduction to Japanese Politics|url=https://books.google.com/books?id=9bcO2TlTQ24C&pg=PA67|accessdate=8 May 2016|date=15 May 2009|publisher=M.E.

The Aikokusha should not be confused with the Aikoku Kōtō, or with various later ultranationalist movements with similar names.
