kustaa

Kustaa is a masculine given name used in Finland. It is the Finnish form of Gustav (Gustaf), a name widely found across the Nordic countries. The root form Gustav is of Germanic origin and is commonly traced to a combination of elements referring to a tribe or group (such as the Geats or Goths) and a staff or support, a construction typical of medieval given names. As the Finnish variant, Kustaa carries the same historical associations in Finnish usage.

In Finland, Kustaa has a long historical presence and appears in older records, literature, and church registries. While it is not among the most popular names for newborns today, it remains part of the country’s onomastic heritage and may be chosen for its traditional or classic connotations. Bearers are typically referred to with formal given-name usage, with possible informal forms in casual contexts.

Related names exist in other languages, including Gustav and Gustaf. The Finnish form Kustaa is distinguished by its phonology and spelling, reflecting Finnish pronunciation and orthographic conventions. The name is primarily encountered in Finnish-speaking contexts and is associated with historical and cultural associations of Nordic naming practices.
