Seredka () is a rural locality (a village) in Megrinskoye Rural Settlement, Chagodoshchensky District, Vologda Oblast, Russia. The population was 19 as of 2002.
Many villages in this region originated between the 16th and 19th centuries as small agrarian or forestry settlements. The wide Volgosa area was historically inhabited by Finno-Ugric peoples, later integrating into the Russian state through Slavic expansion. Rural settlements like Seredka functioned as subsistence farming commuities, or logging and resource based hamlets.
Seredka is located km northeast of Chagoda (the district's administrative centre) by road. Lvov Dvor is the nearest rural locality. It is located in a region dominated by forested landscapes and dispersed rural communities. Volgoda Oblast is part of the East European Plain and lies within the taiga (boreal forest) zone. The terrain is generally flat to a gently rolling incline, roughly 150 to 200 m above sea level. The broader region is rich in natural resources like timber and freshwater.
