Farris is the name of a 20 km long fresh water moraine-dammed lake near the Norwegian coastal town Larvik. The lake would have been a salt water fjord had it not been dammed by an end moraine left by the latest ice age. Farris is drinking water reservoir for some 170.000 people.

Farris is also the product name of a natural mineral water produced in Larvik. The ground water mineral spring and bottling factory is located beneath the forested hilltop Bøkeskogen. The water originates from rainwater falling on Bøkeskogen. The water slowly filters through deposited glacial moraine material and reaches the spring some 15-20 years later, strongly mineralized. The Farris mineral water has been bottled since 1907. A common misconception is that the mineral water comes from the lake Farris, but that is not correct. Ringnes breweries own the rights to the Farris trademark. The products under the Farris brand are sparkling mineral water which also comes with various flavours (including lime and lemon).
