The name Vangaži (German: Wangasch) was first mentioned in the 17th century as the name of a local manor. The name itself is a combination of two words in the Livonian language - vang (field) and aži (place). Since the 17th century there was also a Lutheranchurch in Vangaži. Close to the modern town of Vangaži there were several manufactures which produced paper, glass and copper products.
The modern town started in the 1950s when the concrete factory was founded. In 1957 the village Oktobra ciemats was founded which in 1961 was renamed to Vangaži. In 1992 Vangaži was granted the status of a town.
