Meaning & origin

Petr is a Slavic form of Peter, meaning 'rock' or 'stone'. In the United States, it has never ranked in the top 1000 names, reflecting its status as a cultural import rather than a mainstream choice. The name saw its highest recorded use in 2014, though overall frequency remains low. Its trajectory has been stable, with modest and consistent use over the decades. While no states show significant concentrations, the name is most common among families with Czech or Slovak heritage.

Petr is the Slavic form of Peter, which derives from the Greek Petros, meaning 'rock' or 'stone'. In Christian tradition, Saint Peter was one of the twelve apostles and considered the first bishop of Rome. The name was widely adopted across Europe, with local variants emerging in Slavic languages. It has been consistently used in Czech and Slovak cultures since the Christianization of the region.
