Sofia Nikolaevna Smidovich (Russian: Софья Николаевна Смидович; 24 February 1872 – 24 November 1934) was a Bolshevik revolutionary, feminist and the leader of the Zhenotdel from 1922 to 1924.

[2] She joined the RSDLP in 1898, where she campaigned with fellow feminist revolutionaries such as Alexandria Kollontai.

[3] She became a close and important ally for radical Bolshevik feminists at the time, most notably, Kollontai and Elena Statsova.

Post revolution, it became clear that Smidovich was one of the more conservative Bolshevik feminists and she openly rejected Kollontai's ideas of free love and the destruction of the family unit.

Smidovich was very much in line with government policy at the time, which was against radical ideas of free love.
