Meaning & origin

Petro is a Ukrainian, Belarusian, and Slovak form of Peter, a name of Greek origin meaning "rock" or "stone." In the United States, the name has never appeared in the top 1000 rankings, reflecting its status as a culturally specific name predominantly used within Eastern European immigrant communities. According to Social Security data, Petro was first recorded in 1918, and its peak year of usage came in 1920, though even then it remained uncommon. Its trajectory has been stable over the decades, with low but consistent usage among families preserving Ukrainian or Slovak heritage. As a traditional name in Eastern Europe, Petro carries strong cultural and religious associations, linked to Saint Peter and centuries of use in Slavic nations. For parents seeking a name with ethnic roots and a classic biblical origin, Petro offers a distinct alternative to its more common English counterpart, Peter.

Petro is the Ukrainian, Belarusian, and Slovak variant of Peter, derived from the Greek name Petros (Πέτρος), meaning "stone" or "rock." It entered these languages through Christian influence, as Saint Peter is a prominent figure in the New Testament. The name has been used in Eastern Europe for centuries, particularly in Ukraine and Slovakia.
