Philippe François Pinel, known as Dumanoir (31 July 1806 – 16 November 1865) was a French playwright and librettist.
Dumanoir was born in Capesterre-Belle-Eau, Guadeloupe. He was the son of Mrs. Pinel-Dumanoir, whose family planted the palm trees lining the Allée Dumanoir in Guadeloupe. He left Guadeloupe in 1816. Dumanoir wrote in the theatrical genre of Comédie en vaudevilles. He was director of the Théâtre des Variétés from 1837 to 1839. In 1844, he wrote in collaboration with Adolphe d'Ennery, an eponymous drama about Don César de Bazan, one of the characters in Ruy Blas by Victor Hugo.
