Virrat (Finnish: [ˈʋirːɑt]; Swedish: Virdois) is a town and municipality of Finland.

The town grew rapidly in the middle years of the twentieth century, and by 1950 the population reached more than 12,000.

Virrat acquired town status in 1977, although it had received the right to hold markets three years earlier, in 1974.

More recently the population level has been adversely impacted by the drift of employment opportunities and people to the larger towns.

Apart from the town of Virrat itself, the administratively defined municipality is largely rural, and includes the villages of Äijänneva, Härkönen Jäähdyspohja, Killinkoski, Koro, Kotala, Kurjenkylä, Liedenpohja, Ohtola, Vaskuu, and Vaskivesi.
