Casualty 1900s, broadcast in the U.S. as London Hospital, is a British hospital drama inspired by but otherwise unrelated to BBC One drama Casualty.

It places the viewer in the Receiving Room of the London Hospital, in London's East End. The drama is shot with the pace and action of its modern-day counterpart A&E. Every case and character is based on real cases, characters and events taken from the hospital records, nurses' ward diaries, and memoirs.

It began with a single episode of Casualty 1906, followed by three episodes of Casualty 1907, and six episodes of Casualty 1909.
