Jack Weldon Humphrey (12 January 1901 – 23 March 1967) was a Canadian landscape and figure painter, mainly in watercolour.

He travelled to Europe from 1929 to 1930, studying in Paris with André Lhote and at the Académie de la Grande Chaumière, and in Munich at the Hans Hofmann school.

[2] Returning from France in 1954, he experimented with painted more abstractly in his gouache and oil landscapes, while his watercolours focused on the intimate details of nature.

[3] Humphrey's paintings of the harbour, streets and workers of Saint John in Canada established his reputation as an artist and his work extended to numerous portraits of friends and the city's children.

Humphrey's approach made him a respected member of Montreal's Contemporary Arts Society and the Canadian Group of Painters.
