The Irkutsk Constituency (No.93[a]) is a Russian legislative constituency in Irkutsk Oblast.

It was previously located entirely in metropolitan Irkutsk, however during 2016 reconfiguration the constituency was pushed from Irkutsk to the central Irkutsk Oblast and even parts of former Ust-Orda Buryat Autonomous Okrug, which had its own constituency in 1993-2007.
