Tanjil Bren is a rural locality and former timber town in eastern Victoria, west of the Baw Baw ranges and 60 km north of Moe. It is situated in eucalyptus forests where trees exceeding 100 m in height have been recorded.
In 1936 a local timber- milling firm, Saxton Timber and Trading Pty Ltd, acquired a logging lease on the Eastern Tanjil River. In 1938 the firm selected a sawmill site around which Tanjil Bren was to grow. The name arose from the Tangel pastoral run (1844) and the word Bren was a play on the milling operation being at the speed of a Bren gun.
