The West Wind is a 1917 painting by Canadian artist Tom Thomson. An iconic image, the pine tree at its centre has been described as growing "in the national ethos as our one and only tree in a country of trees". It was painted in the last year of Thomson's life and was one of his final works on canvas. The painting, and a sketch for the painting, are displayed at the Art Gallery of Ontario.

Thomas John Thomson was a Canadian artist active in the early 20th century. During his short career, he produced roughly 400 oil sketches on small wood panels and approximately 50 larger works on canvas. His works consist almost entirely of landscapes, depicting trees, skies, lakes, and rivers. He used broad brush strokes and a liberal application of paint to capture the beauty and colour of the Ontario landscape. Thomson's accidental death by drowning at 39 shortly before the founding of the Group of Seven is seen as a tragedy for Canadian art.
