Bunnik (Dutch pronunciation: [ˈbʏnɪk] ⓘ) is a municipality and village in the province of Utrecht, Netherlands.

The recorded history of the village dates back nearly 2000 years, when the Romans constructed a fort at Fectio (now Vechten) with a harbour facing the river Rhine, which marked the border of the Roman Empire.

In the 8th and 9th century, the villages of Bunninchem (Bunnik), Lodichem (Odijk) and Wercundia (Werkhoven) developed.

Chief interests of Bunnik are its surrounding nature, consisting mainly of forests and farmlands.

The major European construction and services company Royal BAM Group has its headquarters in Bunnik.
