Jacques de Lalaing (1858–1917) was an Anglo-Belgian painter and sculptor, specializing in animals.
He trained as an artist under Jean-François Portaels and Louis Gallait at the Académie Royale des Beaux-Arts in Brussels, showing first as a painter with the group L'Essor.
With the encouragement of Thomas Vinçotte and Jef Lambeaux, Lalaing began to sculpt in 1884.
Along with his fellow animalier sculptors Léon Mignon (1847–1898) and Antoine-Félix Bouré (1831–1883), Lalaing established a distinctively Belgian tradition of animal art, to which the flourishing Antwerp Zoo contributed inspiration.
His works are represented in the collections of museums in Antwerp, Bruges, Brussels, Ghent and Tournai.
