Gertjan

Gertjan is a masculine given name of Dutch origin, used primarily in the Netherlands and in Dutch-speaking regions of Belgium. It is a compound name formed from Gert, a pet form of Gerard, and Jan, the Dutch form of Johannes. The name Gerard itself derives from Germanic elements meaning "spear" and "brave/strong," while Jan means "Yahweh is gracious."

The name has been borne by several Dutch public figures, notably Gertjan Verbeek (born 1961), a football manager and former professional player. The spelling Gert-Jan (with a hyphen) is also common, and the two forms are often treated as the same given name. The name is typically male and can be found across generations, especially among Dutch-speaking populations.
