Semenivka Raion ({{langx|uk|Семенівський район}}) was a raion (district) of Chernihiv Oblast, northern Ukraine. Its administrative centre was located at the city of Semenivka. The raion was abolished on 18 July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Chernihiv Oblast to five. The area of Semenivka Raion was merged into Novhorod-Siverskyi Raion.{{Cite news|title=Про утворення та ліквідацію районів.
