Prefectural elections for the Tokyo Metropolitan Assembly (平成29年/2017年東京都議会議員選挙, Heisei 29-nen/2017-nen Tōkyō togikai giin senkyo, "Heisei 29/2017 election of members of the Tokyo Metropolitan Assembly") were held on 2 July 2017. The 127 members were elected in forty-two electoral districts, seven returning single members elected by first-past-the-post, and thirty-five returning multiple members under single non-transferable vote. Four districts had their magnitude adjusted in this election to match population changes.

The results of the election persuaded Shinzo Abe to call a snap election, and led to the resignation of Renho as Democratic Party leader.
