The Chita Constituency (No.43[a]) is a Russian legislative constituency in Zabaykalsky Krai.

In 1993-2007 the constituency was based in Western Chita Oblast, stretching from Kalarsky District in the north to Krasnochikoysky District in the west, including the city of Chita.

In 2008 Chita Oblast merged with Agin-Buryat Autonomous Okrug to form Zabaykalsky Krai, and newly-configured Chita constituency now includes eastern half of Chita and northern parts of the Krai.
