Middendorf's vole (Microtus middendorffi ) is a species of rodent in the family Cricetidae. It is found only in Russia, most commonly north Siberia.
The common name commemorates Alexander Theodor von Middendorff (1815–1894), a German–Russian naturalist who traveled extensively in Siberia. It is also known as the north Siberian vole or Altai vole.
This vole, along with Microtus gregalis, is one of the primary preys of the Arctic fox on the Yamal Peninsula.
