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 route is signed as an auxiliary route of National Route 236 as well E60 under MLIT's "2016 Proposal for Realization of Expressway Numbering."^[1]

The speed limit is 100 km/h for the entire route. There is only one lane travelling in each direction along the entirety of the expressway.

The first section of the Obihiro-Hiroo Expressway opened on 15 March 2003 between the Dōtō Expressway and Hokkaido Route 1153 in Obihiro. The next addition opened three years later, extending the expressway 13.1 kilometres (8.1 mi) to Hokkaido Route 1157 (Obihiro Airport Road). In 2008 the route was extended to Nakasatsunai. After five years, the next section to Sarabetsu was added. 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.^[3]

The entire expressway is in Hokkaido.
