Vohnja is a village in Kadrina Parish, Lääne-Viru County, in northeastern Estonia.

Vohnja (German: Fonal) manor has a history going back to at least 1504, when the estate was owned by the van der Heyde family.

Later, in 1629 during the time of Swedish rule in Estonia, it is recorded to have belonged to the Oxenstierna family.

[2] The presently visible main building dates from the 1830s and is designed in a Neoclassical style.

Adjacent to the main building are also a number of preserved annexes, such as the estate manager's house (1904), granary (1805) and distillery (19th century).
