Sonkovo (Russian: Сонко́во) is an urban locality (an urban-type settlement) and the administrative center of Sonkovsky District of Tver Oblast, Russia.

[8] Founded by the Russian Greek Orthodox Inkeriköt (Izhorians) in the 17th century and called Savelionkylä (or Savelankylä), the village later changed its name to Savelino (Савелино) due to its proximity to the village of Savelikha, which was built in 1870 during the construction and expansion of the private Rybinsk-Bologoye Railway.

In 1903, the settlement was renamed Sonkovo to avoid possible confusion and a main locomotive depot constructed near the station.

The majority of the dwellings in Sonkovo are wooden although there are many two and three story brick and concrete buildings as well as numerous pre-World War II structures.

The center of the settlement is located next to the train station and its main street, Lenina Avenue, connects to Bezhetsk via the R-85 highway.

One, running from south to north, connects Moscow with Mga via Krasny Kholm and Pestovo.
