Meaning & origin

Jacek is a distinctly Polish masculine name that entered US records in 1965, though it has never been common. Its highest popularity came in 2013, ranking 12,008 in that year, but it has been on a declining trajectory since 2012. As of 2025, only about 1 in 341,615 baby boys are named Jacek, reflecting its rarity outside Polish communities. The name carries deep religious and cultural significance in Poland due to its association with Saint Hyacinth, a 13th-century Dominican missionary. Despite its modest American presence, Jacek remains a meaningful choice for families honoring Polish heritage.

Jacek is the Polish form of the Latin name Hyacinthus, which derives from Greek hyakinthos, the hyacinth flower. In Christian tradition, the name is associated with Saint Hyacinth (1225-1257), a Polish Dominican missionary and saint, who was given the baptismal name Jacek after the flower. The name has been in consistent use in Poland since the Middle Ages, though it remains relatively rare in the United States.
