The United Peasant Party (, abbr. USS) is an agrarian political party in Serbia. Its primary area of strength is in the municipality of Svrljig. It is affiliated with the European People's Party in the Congress of Local and Regional Authorities.
According to the party's website, the United Peasant Party was established in Belgrade in 2000 via a merger of three small peasant parties. At the party's founding meeting, Dragoslav AvramoviÃÂ agreed to be its honorary president; he died the following year. The USS won representation in the Svrljig municipal assembly in the 2000 local elections, and local party leader Milija MiletiÃÂ became mayor of the municipality in 2008.
The USS was not formally registered as a political party until 2010; prior to this time, it was designated as a Citizens' Group. MiletiÃÂ was recognised as the party's leader at the time of its registration and continues to hold this position as of 2025. He is the only member of the USS to have served in the National Assembly, having been first elected in the 2014 Serbian parliamentary election on the electoral list of the Serbian Progressive Party and then re-elected on the same party's lists in the 2016, 2020, 2022, and 2023.
