Kstovo (Russian: Ксто́во) is a town and the administrative center of Kstovsky District in Nizhny Novgorod Oblast, Russia, located on the right bank of the Volga River, 22 kilometers (14 mi) southeast of Nizhny Novgorod, the administrative center of the oblast. Population: 66,657 (2010 Census); 66,944 (2002 Census); 62,414 (1989 Census).
The place name is said to have originated from the Mordvin ksty, meaning "strawberry".
The village of Kstovo was mentioned as early as the 14th century.
With the construction of Novogorkovsky Oil Refinery, which started operations on August 18, 1958,) a new settlement was built a few kilometers to the northwest of the old village of Kstovo, on the high ground between the Volga and the Kudma Rivers. Since then, the western part of the town centered around the original village of Kstovo, and, still quite rural in character, has been commonly referred to as the Old Kstovo (Staroye Kstovo), while the newer eastern part, built in the 1950s and still expanding, is known as the New Kstovo (Novoye Kstovo). As the New Kstovo expanded over the years, it completely or partially displaced several smaller villages.
Kstovo (Russian: Кстово) is the name of several inhabited localities in Russia.
