The Ob constituency (No.181) is a Russian legislative constituency in Tomsk Oblast. During 1993-1995 the constituency covered upstate Tomsk Oblast but Tomsk Oblast lost its second constituency prior to the 1995 election, so both Rural and Urban constituencies were merged into Tomsk constituency. Tomsk Oblast regained its second constituency in 2016 and currently Ob constituency covers parts of Tomsk as well as western Tomsk Oblast.
