The Tōkyō proportional representation block (Hirei [daihyō] Tōkyō burokku (比例[代表]東京ブロック)), or more formally the proportional representation tier "Tokyo Metropolis electoral district" (東京都選挙区, Tōkyō-to senkyo-ku), is one of eleven proportional representation (PR) "blocks", multi-member constituencies for the House of Representatives in the Diet of Japan. It consists solely of the prefecture of Tokyo making it one of two blocks covering only one prefecture, the other being Hokkaido. Following the introduction of proportional voting Tokyo elected 19 representatives by PR in the 1996 general election, and 17 since the election of 2000 when the total number of PR seats was reduced from 200 to 180.
