The People's Federative Party (Bulgarian Section) (Bulgarian: Народна федеративна партия (българска секция)) was a Bulgarian political party in the Ottoman Empire, created after the Young Turk Revolution, by members of the left wing of the Internal Macedonian Adrianople Revolutionary Organization (IMARO). The party functioned for one year from August 1909 until August 1910. The Party decided to name itself Bulgarian Section, since it was hoped that other nationalities from European Turkey would adopt its program and form their own ethnic sections, but this didn't happen. Its main political rival was the Union of the Bulgarian Constitutional Clubs.

The Young Turk Revolution was a constitutionalist revolution in the Ottoman Empire. Revolutionaries belonging to the internal Committee of Union and Progress, an organization of the Young Turks movement, forced Sultan Abdul Hamid II to restore the Constitution, recall the parliament, and schedule an election. Thus began the Second Constitutional Era.
