Henri Philibert Joseph Delmotte (14 March 1822 – 10 July 1884) was a Belgian stage poet and novelist.
Delmotte was born in Baudour, Hainaut and studied jurisprudence and then worked for the government for a time, becoming a commissioner in Nivelles.
However, he soon left public life and moved to Brussels.
He was working in establishing a French-speaking national theatre in Belgium and from 1879 to 1880 wrote handbills and highly polemic newspaper articles.
Beside numerous magazine articles, Delmotte also published books and comedies, in which he describes the contemporary Belgian middle classes.
