The Bryansk constituency (No.77) is a Russian legislative constituency in Bryansk Oblast. The constituency covers southern Bryansk and southern Bryansk Oblast.

The constituency has been represented since 2021 by United Russia deputy Nikolay Valuyev, three-term State Duma member and former professional boxer, who won the open seat, succeeding one-term Liberal Democratic incumbent Boris Paykin after the latter decided to successfully seek re-election only through proportional representation.

1993–2007: Brasovsky District, Bryansk, Bryansky District, Dyatkovo, Dyatkovsky District, Karachevsky District, Komarichsky District, Navlinsky District, Seltso, Sevsky District
The constituency covered eastern edge of Bryansk Oblast, including the oblast capital of Bryansk, cities of Dyatkovo and Seltso.

2016–present: Brasovsky District, Bryansk (Fokinsky, Sovetsky), Bryansky District (Dobrun, Michurinsky, Putyovka, Suponevo, Sven), Karachevsky District, Klimovsky District, Komarichsky District, Navlinsky District, Novozybkov, Novozybkovsky District, Pochepsky District, Pogarsky District, Sevsky District, Starodubsky District, Suzemsky District, Trubchevsky District, Vygonichsky District, Zlynkovsky District
The constituency was re-created for the 2016 election and it retained southern half of Bryansk, its southwestern suburbs and southeastern corner of Bryansk Oblast, losing the rest to new Unecha constituency. This seat instead gained rural southern Bryansk Oblast, including the city Novozybkov, from the former Pochep constituency.
