Jacobus

Meaning & origin

Jacobus is a rare but enduring name with deep historical and religious roots. Currently ranked #12,008 in the United States in 2025, it sees about 1 in every 341,615 baby boys given the name, making it a highly distinctive choice. The name's popularity peaked in 1997, and since 2015 its trajectory has been rising, indicating a slow but steady uptick in modern usage. Jacobus is the Latin form of Jacob, appearing in the Vulgate Bible and used widely in Dutch, Afrikaans, and scholarly contexts. Its strong, classical sound invites nicknames like Koos and Cobus, popular in the Netherlands and South Africa. The name is not tied to any particular region in the U.S., as it does not appear in top states data, suggesting its use is scattered. Jacobus offers a formal, timeless alternative to Jacob, with a rich etymology and a quiet but resilient presence.

Jacobus is the Latin form of the Hebrew name Yaakov (Jacob), meaning 'supplanter' or 'holder of the heel' from the biblical account of Jacob grasping Esau's heel. It entered use through the Latin Vulgate Bible and became a common scholarly and ecclesiastical form in medieval Europe. In Dutch and Afrikaans, Jacobus has been used as a given name in its own right, often shortened to Koos or Cobus.
