The Komsomolsk-na-Amure Constituency (No.70[a]) is a Russian legislative constituency in the Khabarovsk Krai.

In 1993-2007 the constituency was included most of upstate Khabarovsk Krai and the city of Komsomolsk-on-Amur.

However, the Komsomolsk-na-Amure constituency was gerrymandered in 2016, and now consists of not just northern Khabarovsk Krai and Komsomolsk-na-Amure, but also of eastern Khabarovsk and its suburbs.
