Adolf Törngren (27 April 1824 – 3 March 1895) was a Finnish jurist and industrialist.
Törngren studied law degree, but shortly after he inherited significant property and became industrialist.
Törngren operated Nuutajärvi glassworks and later he had a significant role in industrialisation of Tampere.
In 1861 he founded Tampere Linen and Iron Industry Ltd together with Gustaf Wasastjerna.
Törngren was co-founder of shipbuilding and engineering company Helsingfors Skeppsdocka in Helsinki.
His investments drove him into cash crisis, which caused him bankruptcy.
In 1877 Törngren founded Tampere Asphalt- and Roof Membrane Works in old groundwood mill premises.
While there was demand for such products, the company fell into trouble due to Törngren's optimistic business decisions, and he sold it later.
