Tokyo 8th district (東京都第8区, Tōkyō-to dai-hachiku or simply 東京8区, Tōkyō-hachiku) is a single-member constituency of the House of Representatives in the national Diet of Japan.

The district was created in 1994 as part of an electoral reform effort in the Japanese House of Representatives, and was first implemented in the 1996 general election.

Tarō Yamamoto, leader of the Reiwa Shinsengumi, had announced he would run in the district, but he bowed out and endorsed Yoshida.
