'''Volok''' ({{langx|lt|valakas}}, {{langx|pl|włóka}}, {{langx|be|валока}}, {{langx|ru|волока}}) was a late medieval unit of land measurement in the Grand Duchy of Lithuania, Kingdom of Poland and later, the Polish–Lithuanian Commonwealth. It was equal, on average, to {{convert|21.368|ha}} in Lithuania or to {{convert|17.955|ha}} in Poland.<ref name=tarvy/> It was subdivided into 30 or 33 morgens.<ref name=baltr/>
Volok was also a unit that determined taxation and other duties to the state.<ref name=baltr/> Previously, taxes and duties were based on the number of households (see, for example, 1528 census of the Grand Duchy of Lithuania that recorded households as a measure of military duty) or number of horses/bulls needed to work the land. Such system was not exact: households varied greatly in size and in wealth. Therefore, the introduction of voloks marked an important transition to taxes based on area (width times length).<ref name=baltr/>
In Lithuania, it was introduced during the Volok Reform that began in 1547. Officially, voloks were abandoned as a unit after the emancipation reform of 1861, but survived in everyday use until the introduction of the metric system in 1921.<ref name=gudav/>
