Tammiku (de|Eichenhain) is a small borough (et|alevik) in Jõhvi Parish, Ida-Viru County, in northeastern Estonia. It is located about 3km (02miles) southwest of the town of Jõhvi and about 2km (01miles) northwest of Kohtla-Järve's Ahtme district. As of the 2011 census, the settlement's population was 291.[1]
Tammiku was first mentioned as Damicas in 1241 in the Danish Census Book, and later as Tammykass in 1533 and Tammiku-Mõisaküla in 1945. The name (in the genitive case) comes from the common noun tammik 'oak forest', referring to the local vegetation.[2]
Tammiku is the birthplace of Estonian amateur featherweight boxer Evald Seepere (1911–1990).
