Archibald Lampman, FRSC (17 November 1861 – 10 February 1899) was a Canadian poet. He was born at Morpeth, Ontario, a village near Chatham. Lampman attended Trinity College (now part of the University of Toronto).
In 1883, after a brief and unsuccessful attempt at teaching high school in Orangeville, Ontario, Lampman took an appointment as a low-paid clerk in the Post Office Department, Ottawa, a position he held for the rest of his life.
Lampman associated with Charles G. D. Roberts, Susanna Moodie, Catherine Parr Traill, Duncan Campbell Scott, and William Wilfred Campbell. He was one of the Confederation Poets and was elected a Fellow of the Royal Society of Canada in 1895. Lampman died in Ottawa at the age of 37.
He is widely regarded as Canada's finest 19th century English language poet. Lampman's poetry concerns Canada's rural life and the wonders of nature and can be compared to British romantic and nature poetry contemporary to his life. Lampman's ability to write detailed, meaningful, poems that depicted traditional Canadian and Native American life was one of his greatest triumphs as a poet and probably one of the reasons why his work has had lasting import in the Canadian canon.
An annual literary prize, the Archibald Lampman Award, is named in Lampman's honour, as is the town of Lampman, Saskatchewan.  A small town of approximately 730 people, containing prestigious families such as the Veroba family, Lampman is situated close to the City of Estevan, the eighth largest city in Saskatchewan very close to bordering the United States of America.
The Canadian singer/songwriter Loreena McKennitt adapted Lampman's poem "Snow" as a song, writing original music while keeping as the lyrics the poem verbatim. This adaptation appears on McKennitt's album To Drive the Cold Winter Away (1987) and also in a different version on her EP, A Winter Garden: Five Songs for the Season (1995).
