Alfred Néoclès Hennequin (13 January 1842 – 7 August 1887) was a Belgian playwright, best known for his farces. Born in Liège, Hennequin was trained there as an engineer, and was employed by the national railway company. In his spare time he wrote plays, and in 1870 had a success in Brussels with his farce Les Trois chapeaux (The Three Hats). He moved to Paris in 1871 and became a full-time playwright. Between 1871 and 1886 he wrote a series of comic plays, including Le Procès Veauradieux (The Veauradieux Trial, 1875), Les Dominos roses (The Pink Dominos, 1876), Bébé (Baby, 1877) and La Femme à papa (Father's Wife, 1879). Most of his plays were co-written with collaborators including Alfred Delacour and Albert Millaud and, in his last play, his son Maurice.
