Meaning & origin

Maciej is a distinctly Polish name with deep roots in Christian tradition. According to U.S. Social Security data, the name has been recorded since at least 1982, with a peak in popularity in 1996. Although it has no state-level concentration in current data, its usage trajectory shows stability, indicating a steady but modest presence among Polish-American families and others seeking a name with cultural weight. The name is derived from the Hebrew Mattityahu, connecting it to the apostle Matthias, and has maintained its form in Polish for centuries without significant adaptation into other languages.

Maciej is the Polish form of Matthias, which derives from the Greek name Matthaios, itself from the Hebrew Mattityahu, meaning 'gift of Yahweh'. In Poland, Maciej has been a traditional name for centuries, often associated with Saint Matthias, the apostle chosen to replace Judas. It has remained steadily in use, particularly among Catholic families, and is one of the few Polish names that is almost exclusively used in its native form rather than imported variants.
