Tōyako (洞爺湖町, Tōyako-chō) is a town in Iburi Subprefecture, Hokkaido, Japan. It was formed on March 23, 2006, through the merger of the town of Abuta and the village of Tōya. As of 1 October 2020, the town has an estimated population of 8,442, and a population density of 47 persons per km. The total area is 180.54 km.

The name of the town was derived from the nearby Lake Tōya (Tōya-ko).

On April 23, 2007, the town and its surrounding area was announced as the site of the 2008 summer G8 summit. Japan's former Prime Minister Shinzo Abe reportedly chose the area because of its proximity to many famous sightseeing grounds, such as Lake Tōya and Tōyako Onsen.
