Meaning & origin

Izaak is a distinctive variant spelling of Isaac, a name with deep biblical roots. In the United States, Izaak first appeared on the Social Security Administration's records in 1972, and it saw its peak popularity in 2011. Since then, its usage has been falling. In 2025, the name ranked 2991st, with about 1 in 41,660 boys receiving the name. Geographically, Izaak has been most common in Connecticut, Florida, and Texas. While Isaac has remained a top-50 mainstay for decades, the Izaak spelling offers a more unique twist, appealing to parents who appreciate the traditional meaning and sound but want a less common variant. The name carries the same joyful etymology as Isaac, derived from the Hebrew Yitzchak, 'he will laugh,' and is used widely across cultures with slight variations.

Izaak is a Dutch and Polish variant spelling of Isaac, which derives from the Hebrew Yitzchak, meaning 'he will laugh' or 'he rejoices.' The name appears in the Old Testament as the son of Abraham and Sarah, and it has been used widely in Christian, Jewish, and Muslim traditions. The alternative spelling Izaak is especially common in the Netherlands and Poland, and it has been adopted in English-speaking countries as a distinctive variant.
