The following is a list of winners and nominees in French-language categories for the Trillium Book Award, a Canadian literary award presented by Ontario Creates to honour books published by writers resident in the province of Ontario. Separate awards have been presented for English-language literature since 1994; for the winners and nominees in English-language categories, see Trillium Book Award, English.

From 1994 to 2002, a single annual award was presented for French-language books regardless of genre; in 2002, an award for best first book of poetry was introduced for francophone poets, but was only presented once, and established poets were still considered for the main all-genre award.

In 2003, the award was fully split into separate categories for prose and poetry; however, in the second year of the poetry categories, the program failed to receive a sufficient number of submissions to present a French-language poetry award. The prize money that had been earmarked for the French poetry category was instead used that year to create an academic scholarship for French-language creative writing students in Ontario, and the category was further adjusted so that it now encompasses a two-year eligibility period instead of one, and alternates with a two-year category for French-language children's literature.

In 2024, for the first time since the two-year alternation for poetry and children's literature was introduced, the two-year eligibility period still did not produce enough French poetry titles to present an award in that category."Zalika Reid-Benta and Britta Badour among finalists for 2024 Trillium Book Awards".
