Hokkaidō 9th district is a constituency of the House of Representatives in the Diet of Japan (national legislature).

The LDP had nominated Hokkaidō prefectural assemblyman and former Olympic speed skater Manabu Horii as their candidate in July 2012.

In the 2000, 2003 and 2005 general elections, the Liberal Democratic Party's candidate was Hirofumi Iwakura, later mayor of Tomakomai, Iburi Subprefecture.

Before the 1994 electoral reform, the area had been part of Hokkaido 4th district where five representatives were elected by single non-transferable vote.

Yukio Hatoyama (New Party Sakigake), Tatsuo Takahashi (LDP) and Tomoko Kami (JCP) had already stood as candidates there in 1993.
