Berndt Wilhelm Schauman (8 November 1857 – 14 November 1911) was a Finnish industrialist, the most important in Jakobstad at the beginning of the 20th century.
He was the older brother of Ossian Schauman, and a member of the Schauman noble family.
Wilhelm Schauman's first industrial installation was a small chicory (coffee additive/substitute) factory, which he founded in 1883.
He was also involved in the local tobacco factory as part of the management.
Apart from this, he continuously founded new enterprises such as a sugar refinery, a steam-powered saw mill and a plywood factory, which was the first of its kind in Finland.
His enterprises soon expanded beyond the borders of Jakobstad.
A paper and pulp mill was later built in Jakobstad, and remains today as the largest factory in Jakobstad.
It is owned by UPM-Kymmene, as a result of a merger in 1988.
