Kociewie is an ethnocultural region in the eastern part of Tuchola Forest, in northern Poland, Pomerania, south of Gdańsk. Its cultural capital is Starogard Gdański, and the biggest town is Tczew. The region has about 250,000 inhabitants. It has well-developed industry and agriculture.
The Kociewiacy are a Polish ethnographical group. Most of the Kociewiacy are Roman Catholics. They live next to a far more prominent ethnic group in the area, the Kashubians. In the 2011 census, 3065 individuals declared themselves as Kociewiacy, an increase since the census of 2002, when nobody identified as such. Kocievian dialect, unlike Kashubian, is mostly intelligible with mainstream Polish language. Despite geographic proximity, these two dialects are very dissimilar, with Kocievian being much closer to Kuyavian, to the point of some scholars calling it a variant of that dialect.
