Louis Dantin was the pen name of Eugène Seers (November 28, 1865 – January 17, 1945), a Canadian writer and editor from Quebec.

[1] Originally from Beauharnois, Quebec, he studied at the Collège de Montréal and later attended seminary to become a Roman Catholic priest.

[1] He subsequently left the priesthood in 1903, marrying Clotilde Lacroix and moving to Boston, Massachusetts, where he worked as a printer for Harvard University Press.

[1] Two writers, Claude-Henri Grignon in his 1936 Les Pamphlets de Valdombre and Yvette Francoli in her 2013 Le Naufragé du Vaisseau d'or, have alleged that Dantin was the actual author of most of the poetry that is credited to Nelligan.

[3] In 2016, the University of Ottawa's literary journal, @nalyses, published an article by Annette Hayward and Christian Vandendorpe that rejected the claim based on textual comparisons of the poetry that is credited to Nelligan with Dantin's writings.
