Tammiku is a village in Vinni Parish, Lääne-Viru County, in northeastern Estonia.

Name

Tammiku was attested in written sources as Pamicus in 1241, Pammekule in 1345, and Tamyckass in 1545. According to the historian Paul Johansen, the initial P in the earliest attestations should be read as a T. In the 17th century, the village disappeared and Tammik manor was built, and then in 1765 the surrounding area became a village again. Assuming that the earliest attestations actually began with T, the name (in the genitive case) comes from the common noun tammik 'oak forest', referring to the local vegetation.
