Brevik (Norwegian pronunciation: [ˈbrêːviːk] ⓘ) is a town in Porsgrunn Municipality in Telemark county, Norway.

The town is located on the far end of Eidanger peninsula (Eidangerhalvøya), and was a former export centre for ice and timber.

[4] Brevik is located about 10 kilometres (6.2 mi) to the south of the town of Porsgrunn in a very large urban area.

It is considered part of the Porsgrunn/Skien metropolitan area by Statistics Norway, so Brevik's population is not tracked separately.

[4] The growing village and harbour of Brevig (later spelled Brevik) was historically part of the parish of Eidanger.

The official blazon is "Azure, three bars argent" (Norwegian: Tre sølv bjelker på blå bunn).

The charge has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.
