Aloïs Boudry was a Belgian painter known for his portraits, still lifes and interiors.

He studied at the art schools in Ypres and Roeselare and finished at the Royal Academy of Fine Arts (Antwerp), where his teachers were Nicaise De Keyser and Jozef Van Lerius.

In 1885, he joined "Als ik Kan" (If I Can), an association of visual artists devoted to preserving traditional methods. He participated in the exposition "Brussels International 1910", where he won a silver medal. When the seaside resort of Knokke-Heist began a promotional campaign in 1913, he designed the posters, which became well-known.

At the outbreak of World War I, he fled to England and established himself as a portraitist. In 1917, he moved to Italy to await the end of the war, then returned to Belgium.

Wherever he was, he sought out humble people as the subjects for his paintings. His depictions of the fisherman of Nieuwpoort are especially popular. Many of them can be seen at the National Fishery Museum in Oostduinkerke.

His son, Robert (1872-1961), was also a painter, as was his grandson Paul [fr] (1913-1976). His great-granddaughter, Nele, is currently a painter in Ghent.
