Korotoyak (Russian: Коротояк) is a rural locality (a selo) in Ostrogozhsky District of Voronezh Oblast, Russia,[1] located on the right bank of the Don River.
[citation needed] It was established in 1642 as one of the forts in the Belgorod Defensive Line.
[citation needed] The name is derived from the Korotoyachka River which enters the Don nearby.
[citation needed] Some of the first Russian warships were built in Korotoyak ca. 1700.
Peter the Great is known to have inspected the local shipbuilding yard in person.
