Owen Hall ((born Dublin, 10 April 1853, died Harrogate, 9 April 1907) was the pen name of 19th and early 20th century theatre critic James Davis when writing for the stage. He wrote the librettos for several very successful shows, including A Gaiety Girl, The Geisha and A Greek Slave.
The change of career from critic to librettist came after writing a particularly caustic review of a George Edwardes production. The producer challenged Davis to try to do better. The result was A Gaiety Girl, and further success followed.
He was a keen gambler. It is said that the name Owen Hall was chosen as an ironic nod ('owing all') towards his extensive debts. This suspicion is reinforced by another pseudonym, Payne Nunn.
