Ethel Seath (February 5, 1879 – April 10, 1963) was a Canadian artist. Seath was a prominent figure on the Montreal art scene for sixty years and her artistic work included being a painter, printmaker (etching), commercial artist, and art instructor at the all-girls private school, The Study, in Montreal. Seath’s oil and watercolour paintings were primarily still life and landscape, exploring colour and adding abstract elements to everyday scenes.
