Robert Garnier (1544–1590) is a French tragic poet.
He publishes his first work while still a law-student at Toulouse, where he wins a prize (1565) in the Académie des Jeux Floraux.
It is a collection of lyrical pieces, now lost, entitled Plaintes amoureuses de Robert Garnier (1565).
After some legal practice at the Parisian bar, he becomes conseiller du roi au siege présidial and sénéchaussé of Maine, his native district, and later lieutenant-général criminel.
His friend Lacroix du Maine says that he enjoyed a great reputation as an orator.
He is a distinguished magistrate, of considerable weight in his native province, who gives his leisure to literature, and whose merits as a poet are fully recognized by his own generation.
