Rina Lasnier, GOQ (6 August 1915 – 9 May 1997) was a Québécois Canadian poet.

Born in St-Grégoire d'Iberville-Mont-Saint-Grégoire, Quebec, she attended Collège Marguerite Bourgeoys and the Université de Montréal.

Although she was the author of several plays, including Féerie indienne (her first published book in 1939), she is chiefly remembered as a poet.

Lasnier was the recipient of many honours, including the Prix David (1943 and 1974), the Ludger-Duvernay Prize (1957), the Molson Prize (1971), the Prix France-Canada (1973) and the Lorne Pierce Medal (1974).

She lived most her adult life in Joliette but returned to the St.-Jean-sur-Richelieu during her final years.
