The Hokkaidō proportional representation block (比例[代表]北海道ブロック, Hirei [daihyō] Hokkaidō burokku) or in official usage the "Hokkaidō electoral district" (北海道選挙区, Hokkaidō senkyo-ku) is one of eleven proportional representation (PR) blocks for the House of Representatives in the Diet of Japan.

It consists of Hokkaidō and is one of two PR blocks that covers only one prefecture, the other being Tokyo.

In 2000, when the combined vote of the two major parties reached a low of 56.8%, the Social Democratic Party managed to obtain a seat with only 8.9% of the vote (for a detailed explanation, see D'Hondt method).

In the first three elections in which it fielded candidates, it managed to obtain the third-largest vote share and one seat.

In 2012, the Liberal Democratic Party became first party in the Hokkaidō proportional election for the first time, and has narrowly held onto that position in 2014 and 2017.
