The Iskitim constituency (No.137[a]) is a Russian legislative constituency in Novosibirsk Oblast.

Until 2007, the constituency covered suburban and rural territories around Novosibirsk in eastern Novosibirsk Oblast.

However, in 2015 the constituency was heavily gerrymandered: it currently takes parts of Novosibirsk itself and stretches alongside oblast's southern border as far as Bagan in the west.
