Prem Bahadur Singh () is a Nepalese politician. He is the chairman of the Samajbadi Prajatantrik Janata Party, Nepal. He was previously a political leader of the Communist Party of Nepal (Unified Marxist-Leninist).

Singh won the Kalikot-1 seat in the 1999 parliamentary election as a CPN(UML) candidate. Singh got 10813 votes, defeating the Nepali Congress candidate Netra Bahadur Shahi.

Singh was expelled from CPN(UML) on the ground of supporting the monarchy. After the royal coup d'etat in February 2005, Singh was appointed Minister by King Gyanendra.

After the 2008 Constituent Assembly election, in which SPJPN won one Proportional Representation seat, Singh was selected to represent the party in the Constituent Assembly.
