Meaning & origin
Petar, the South Slavic form of Peter, has been in use in the United States since at least 1963, though it has never been common nationally. In 2025, it ranked 6,143 and was given to roughly 1 in 122,005 newborns, reflecting its niche appeal. The name saw its peak usage in 2020, and its trajectory has been rising since 1991, indicating a slow but steady increase in interest among families with Balkan heritage or those seeking a distinctive variant of a classic name. Petar is most popular in Illinois, where a sizable Croatian and Serbian community resides. The name carries a strong biblical and royal legacy, being associated with Saint Peter, the first pope, and several medieval kings of Serbia, Croatia, and Bulgaria.
Petar is a South Slavic form of Peter, derived from the Greek Petros (rock). It has been a common name across the Balkans for centuries, popularized by Saint Peter and many medieval monarchs.
