The Ruin (Ukrainian: Руїна, romanized: Ruyina) is a historical term introduced by the Cossack chronicle writer Samiilo Velychko (1670–1728) for the political situation in Ukrainian history during the second half of the 17th century.

The timeframe of the period varies among historians:

Some historians such as Mykola Kostomarov define the period between 1663 and 1687, associating it with the three Moscow-appointed hetmans of Left-bank Ukraine (Briukhovetsky, Mnohohrishny and Samoylovych).
Other historians interpret the period between 1660 and 1687, from the Treaty of Chudnov that led to division among the Cossack community.
Borys Krupnytsky considered the timeframe as 1657–1687, from the death of hetman Bohdan Khmelnytsky in 1657, particularly the Pushkar-Barabash Mutiny, until the ascension of hetman Ivan Mazepa in 1687.

The period was characterised by continuous strife, civil war, and foreign intervention by neighbours of Ukraine. A Ukrainian saying of the time, Від Богдана до Івана не було гетьмана "From Bohdan to Ivan, there was no hetman [in between]", accurately summarises the chaotic events of this period.
