The Obihiro-Hiroo Expressway (帯広広尾自動車道, Obihiro-Hiroo Jidōsha-dō) is an incomplete two-lane national expressway in Tokachi Subprefecture, Hokkaido.

It is owned and operated primarily by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), but has a short section maintained and tolled by the East Nippon Expressway Company at its northern terminus with the Dōtō Expressway.

The next addition opened three years later, extending the expressway 13.1 kilometres (8.1 mi) to Hokkaido Route 1157 (Obihiro Airport Road).

As of February 2019, the most recent addition was completed in 2015, extending the route to its current southern terminus at Chūrui-Taiki Interchange.

[2] There are plans to extend the expressway 15.1 kilometres (9.4 mi) south from Chūrui-Taiki Interchange in Taiki to Hiroo.
