Tver Oblast Duma, Regional parliament in Tver, Russia.

The Tver Oblast Duma is the regional legislative body where elected representatives gather to debate and pass laws. The building houses the chambers and committees responsible for managing regional affairs.

The assembly traces its origin to the Kalinin Oblast Council of People's Deputies; its last convocation was elected in March 1990 under chairman M. A. Shestov. After the oblast was renamed Tver in 1990, the body became the Tver Oblast Council. On 20 March 1994 the first Legislative Assembly was elected by direct secret ballot, and it held its first session on 31 March 1994, adopting a declaration of its powers; Vladimir Kurbatov became its first chairman.

The assembly's name changed with the region: the body was the Kalinin Oblast Council of People's Deputies until the Presidium of the Supreme Soviet of the RSFSR renamed Kalinin Oblast as Tver Oblast on 17 July 1990. The first Legislative Assembly of the new name was elected on 20 March 1994, and its first sitting on 31 March 1994 adopted a declaration of its powers.

The assembly sits at Sovetskaya Street 33 in central Tver, in the eight-storey building designed by architect Vladimir Obraztsov and completed in 1969. Sessions of the 40 deputies are held in this building; visitors should confirm access conditions with the assembly's office beforehand rather than assume open doors.

The assembly sits in an eight-storey building at Sovetskaya Street 33, built in 1969 to a design by architect Vladimir Obraztsov for the Kalinin Regional Committee of the Communist Party. Deputies first met there on 31 March 1994, when the new body adopted a declaration of its legislative powers.
