Aloys (Alois) Jean Maria Joseph, Viscount[1] Van de Vyvere (8 June 1871 – 22 October 1961) was a Belgian Catholic Party politician.

Born in Tielt, Van de Vyvere studied law and philosophy and worked as a lawyer in Ghent, where he served as a local councillor between 1909 and 1911.

In 1911 he was elected to the Belgian Chamber of Representatives for Roeselare and Tielt with the strong support of the Boerenbond (farmers' union).

On 25 February 1920, he cofounded the oil company Compagnie Financière Belge des Pétroles (Petrofina), together with Fernand and Hector Carlier.

Becoming the prime minister of Belgium in 1925,[3] he presided over a party and cabinet in crisis, and his government fell after only a month.
