Cobalt is a town in Timiskaming District, Ontario, Canada. It had a population of 989 at the 2021 census.

In the early 1900s, the area was heavily mined for silver; the silver ore also contained cobalt. By 1910, the community was the fourth highest producer of silver in the world. Mining declined significantly by the 1930s, together with the local population. In late 2017 one publication referred to Cobalt as a ghost town, but the high demand for cobalt, used in making batteries for mobile devices and electric vehicles, is leading to great interest in the area among mining companies.
