Adolphe Stoclet (French pronunciation: [adɔlf stɔklɛ]; 30 September 1871 – 3 November 1949) was a Belgian engineer, financier and noted collector.

[2] After studying civil engineering at the Free University of Brussels, he was employed by Italian and Austrian railway companies from 1894 onwards.

After his father's death, Stoclet became one of the directors of the Société Générale de Belgique, which for many years was one of the largest holding companies in Belgium and owned about forty different enterprises, including banks, arms factories, and mines in the Belgian Congo.

Stoclet had his own office there refurbished by the architect Josef Hoffmann, one of the masters of the Vienna Secession (and later, the Wiener Werkstätte).

Hoffmann left much of the interior decoration for the Stoclet Palace to the painters Gustav Klimt and Fernand Khnopff.
