Siedlce Governorate was an administrative-territorial unit (guberniya) of Congress Poland of the Russian Empire.
It was created in 1867 from the division of the Lublin Governorate. It was in fact a recreation of the older Podlasie Governorate, but now renamed to Siedlce Governorate. Siedlce Governorate was abolished in 1912 and its territory was divided between Lublin Governorate, Łomża Governorate and the newly created Kholm Governorate.
