Thingvalla Township was organized in 1882, and, along with Gardar, Beaulieu and Akra Townships, was known as one of the "Icelandic Townships," due to the large population of Icelanders who had settled here. Thingvalla is named after Þingvellir in Iceland, the site of Iceland's first parliament (930–1789), and now home to a historical national park. Thingvalla roughly translates to "parliament meadows."
Thingvalla Township was a "double township," spanning two full survey townships. In 1886, the southern part of the township was organized separately as Gardar Township, named after Gardar Svavarsson, who was reportedly the first Scandinavian to visit Iceland.
