Federal Socialist Party (Nepali: संघिय समाजवादी पार्टी) was a political party of Nepal led by Ashok Rai formed in 2012.

Ashok Rai, who was the vice-chair of CPN (UML) and Rajendra Prasad Shrestha, a central committee member of the party, broke away from the CPN (UML) to form the Federal Socialist Party in November 2012.

They accused the CPN (UML) leadership of not listening to the aspirations of Janajati leaders within the party and organized a new party to contest the 2013 Constituent Assembly election.

The party merged with Madhesi Jana Adhikar Forum, Nepal and Khas Samabesi Party in June 2015 to form the Federal Socialist Forum, Nepal.
