bJ

Bj is a masculine given name used primarily in Scandinavian countries. It commonly appears as a shortened form of longer names such as Björn in Sweden and Norway or Bjørnar in Norway, though it is also used as a standalone given name in some cases. The form is typically informal and chosen for its concise, contemporary sound.

The name derives from Old Norse Bjǫrn, meaning "bear," a common element in Nordic personal names. As a diminutive, Bj shares its origin with a broader family of names built around animal or natural imagery.

In modern usage, Bj remains more prevalent in Scandinavian naming practices, with its popularity varying by country and era. In addition to being a given name, it may appear as an initialism in contexts where initials identify a person or title (for example, B.J.). In official registries, the full forms Björn or Bjørnar are more likely to appear, while Bj is often encountered as a nickname or informal form.
