Meaning & origin
Zack is a short, punchy name that has been in use in the United States since at least 1880, when it was first recorded. Its popularity peaked early, in 1883, and it has since experienced a long decline. In 2025, it ranked 1,425th, with roughly 1 in 13,556 boys receiving the name. The name has been on a downward trajectory since 2009. Historically, Zack has been most common in New Jersey, New York, and Florida. Despite its decline, Zack remains a familiar and straightforward choice, often seen as an informal variant of Zachary.
Zack is primarily a diminutive of Zachary or Zachariah, names derived from the Hebrew Zechariah, meaning 'God has remembered'. It has been used as an independent given name in English-speaking countries since the 19th century. The spelling with a 'Z' rather than 'J' reflects the Greek-influenced form.
