Its seat is the village of Kolbudy, which lies approximately 11 kilometres (7 mi) west of Pruszcz Gdański and 15 km (9 mi) south-west of the regional capital Gdańsk.

The gmina covers an area of 82.8 square kilometres (32.0 sq mi), and as of 2006 its total population is 12,042.

To 1920, the terrain was divided between the counties of Kartuzy and Gdańsk.

After Germany attacked Poland and annexed the free city, it became part of Nazi Germany until the Soviets liberated it in the East Pomeranian offensive.

On 30 March 1945 the Gdańsk Voivodeship was created and the gmina was incorporated into it.
