Grun

Grun is a surname of German origin. It is a non-diacritic variant of the name Grün, which means “green” in German. The form Grun is common in English-speaking contexts and in diaspora communities where umlauts are not used. The name likely originated as a toponymic or descriptive nickname, referring to a person associated with a green space, pasture, or place named for its greenery, though exact etymologies vary by family.

In modern use, Grun occurs among German-speaking populations and their descendants in Europe, North America, and elsewhere. It is one of several orthographic variants of the name, alongside Grün, Gruen, and Gruhn. Because it is a surname, individuals bearing the name Grun have participated in many fields, but there is no single notable bearer that defines the name.

The spelling Grun may also appear in historical documents that originally used the umlaut form or in transliterations that drop diacritics. In some cases, Grun may be encountered as part of place names or fictional works, but these uses are not standardized and depend on local naming conventions.
