Gästrikland (Swedish pronunciation: [ˈjɛ̌sːtrɪkland] ⓘ) is a historical province or landskap on the eastern coast of Sweden.

The traditional provinces of Sweden serve no administrative or political purposes, but are historical and cultural entities.

Gästrikland is often called the gate to Norrland (the northern Sweden part that is traditionally considered scarcely populated, largely unexplored until the 15th century, and with a terrain dominated by forests, mountains and lakes).

The main parts of Gästrikland consists of plains, which in the south and east transcends into fertile agricultural areas.

To the north the west the terrain becomes hilly and forest covered, unsuitable for agrarian tasks.
