The Obninsk constituency (No.100) is a Russian legislative constituency in Kaluga Oblast in 1993–2007 and 2016–2026. The constituency covered part of Kaluga, eastern and southern Kaluga Oblast. After 2025 redistricting Kaluga Oblast lost one of its two constituencies, so Obninsk constituency was dissolved and merged with Kaluga constituency.
The constituency was last represented by United Russia deputy Gennady Sklyar, non-profit president and former Russian Television and Radio Broadcasting Network general director. Sklyar was re-elected to the State Duma in 2026 in the Kaluga constituency.
