A selsoviet (Belarusian: сельсавет, romanized: sieł'saviet; Russian: сельсовет, romanized: sel'sovet, IPA: [sʲɪlʲsɐˈvʲet]; Ukrainian: сільрада, romanized: sil'rada) is the shortened name for Selsky soviet, i.e., rural council (Belarusian: се́льскi саве́т; Russian: се́льский сове́т; Ukrainian: сільська́ ра́да). It has three closely related meanings:

Selsoviets were the lowest level of administrative division in rural areas in the Soviet Union. After the dissolution of the Soviet Union, they were preserved as a third tier of administrative-territorial division throughout Ukraine, Belarus, and many of the federal subjects of Russia.

A selsoviet is a rural administrative division of a raion (district) that includes one or several smaller rural localities and is in a subordination to its respective raion administration.

The name refers to the local rural self-administration, the rural soviet (council), a part of the Soviet system of administration. The head of a selsoviet is called chairman, who had to be appointed by higher administration.

A December 24, 1917 decree of Sovnarkom initiated the reform of the administrative division inherited from the Russian Empire by which all local power must belong to soviets of the corresponding level of hierarchy. The reform was finalized in 1924.

For a considerable period of Soviet history, passports of rural residents were stored in selsoviet offices, and people could not move outside their area of residence without the permission of selsoviet.

Rural councils of Belarus are subordinated to districts of Belarus. If a rural council includes agrotowns, then one of them is the administrative center of the rural council, with some exceptions.

The system was introduced in 1924, when the whole Soviet Union replaced its administrative division inherited from the Russian Empire.
