Jules Simon Troubat (1836–1914) was a French littérateur, born at Montpellier. He was the last secretary of Sainte-Beuve, one of his testamentary executors, and his legatee. He published a number of posthumous works of Sainte-Beuve, such as his Correspondance, an unfinished monograph on Proudhon, and three volumes of articles originally contributed to the Premiers lundis. Troubat himself wrote:

• Souvenirs et indiscrétions (1875)
• Notes et pensées (1888)
• Souvenirs du dernier secrétaire de Sainte-Beuve (1890)
• Essais critiques (1902)
• Sainte-Beuve intime et familier (1903)
• Souvenirs sur Champfleury et le rélisme (1905)
