The Fukui at-large district (Japanese: 福井県選挙区, Hepburn: Fukui-ken senkyoku) is a constituency that represents Fukui Prefecture in the House of Councillors in the Diet of Japan.

Class of 2022: The constituency represents the entire population of Fukui Prefecture.

The district elects two Councillors to six-year terms, one at alternating elections held every three years.

The district has 644,447 registered voters as of September 2015.

[2] Following the merger of the Tottori and Shimane districts into the Tottori-Shimane at-large district and the Tokushima and Kochi districts into the Tokushima-Kochi at-large district in 2015, Fukui became the electorate with the smallest population, thus making it the standard for measuring malapportionment in other districts.
