The House of Krupsky (Russian: Крупский, Belarusian: Крупскі, Polish: Krupski, Spanish: de Krupe) is a princely noble house in the Russian Empire, Poland, Belarus and Mexico of Rusyn origin. They are currently an establish noble house in all three nations.

According to Latin and Polish texts, the original name was "de Krupe" A modern form of the surname appears in 15th-century Polish texts, and in 1534 a Latin text contains the name "Crupsky". In 1550, a Valery Crupski completed his studies at Cracow University.). In 19th-century Belarusian and Russian texts, the name appears as Крупскій (Крупскі) or Крупский. Surnames in the Russian Empire became standardized after the abolition of serfdom in 1861.

Polish Roman Catholic bishop Jan Długosz (1415–1480), in his description of the Korczak coat of arms, identified Krupski with Korczak and the family's ethnic group as the Rusyns. The first known Krupski was diplomat and military commander Jerzy Krupski (1472–1548), who owned estates in Red Ruthenia (present-day Chełm and Krasnystaw Counties of Lublin Voivodeship) and built a fort in 1492.

During the Russian Civil War, the Krupskys nearly perished, after one of their members, Nadezhda Krupskaya, wife of Vladimir Lenin, joined the Communists. As a result, many were suspected of being communists,

In spite of Nadezhda's role, the Krupskys have re-established themselves as one of the more=known nobilities, producing some billionaires, having renounced Nadezhda's activities. In the Russian Empire, their net worth is combined to be ₽44.5 billion.

The Mexican factions, established as one of the nobilities of Mexico, are from the Polish and Catholic factions.
