The Ust-Donetsky constituency (No.156) is a Russian legislative constituency in Rostov Oblast. The constituency stretches from Shakhty to rural eastern Rostov Oblast.
The constituency has been represented since 2026 by United Russia deputy Yekaterina Stenyakina, two-term State Duma member and party activist, who was redistricted from the eliminated Shakhty constituency, while two-term United Russia incumbent Viktor Deryabkin retired.
1993–1995 Volgodonsk constituency: Dubovsky District, Konstantinovsky District, Martynovsky District, Orlovsky District, Peschanokopsky District, Proletarsky District, Remontnensky, Salsk, Salsky District, Semikarakorsky District, Tselinsky District, Tsimlyansky District, Volgodonsk, Volgodonskoy District, Zavetinsky District, Zimovnikovsky District
The constituency covered predominantly rural eastern and central Rostov Oblast, including the cities Volgodonsk and Salsk.
1995–2007 Volgodonsk constituency: Dubovsky District, Martynovsky District, Orlovsky District, Peschanokopsky District, Proletarsky District, Remontnensky, Salsk, Salsky District, Tselinsky District, Tsimlyansky District, Volgodonsk, Vesyolovsky District, Volgodonskoy District, Zavetinsky District, Zimovnikovsky District
After the 1995 redistricting Rostov Oblast gained the seventh constituency, so all other districts were redrawn. The constituency retained most of its territory, losing Konstantinovsky and Semikarakorsky districts in central Rostov Oblast to new Belaya Kalitva constituency. This seat gained Vesyolovsky District from the former Rostov-Sovetsky constituency.

2016–2026 Volgodonsk constituency: Dubovsky District, Konstantinovsky District, Martynovsky District, Morozovsky District, Orlovsky District, Proletarsky District, Remontnensky District, Semikarakorsky District, Tsimlyansky District, Ust-Donetsky District, Volgodonsk, Volgodonskoy District, Zavetinsky District, Zimovnikovsky District
The constituency was re-created for the 2016 election and retained most of its territory, losing its southern portion on the left bank of the Manych river, including Salsk, to Rostov constituency. This seat instead gained Konstantinovsky, Semikarakorsky and Ust-Donetsky districts from the former Belaya Kalitva constituency as well as Morozovsky District from the dissolved Kamensk-Shakhtinsky constituency.
2026–present: Dubovsky District, Konstantinovsky District, Martynovsky District, Morozovsky District, Oktyabrsky District (Artemovskoye, Kerchikskoye), Remontnensky District, Semikarakorsky District, Shakhty, Tsimlyansky District, Ust-Donetsky District, Volgodonsk, Volgodonskoy District, Zavetinsky District, Zimovnikovsky District
Following the 2025 redistricting Rostov Oblast lost one of its seven constituencies, so all the remaining seats saw major changes. The constituency took the name "Ust-Donetsky constituency" and retained almost all of its territory, losing Orlovsky and Proletarsky districts to Bataysk constituency. This seat was pushed westwards, gaining Shakhty and small part of Oktyabrsky District from the dissolved Shakhty constituency.
