The Warden is the first novel in Anthony Trollope's series known as the "Chronicles of Barsetshire", published in 1855. It was his fourth novel.

The Warden concerns Mr Septimus Harding, the meek, elderly warden of Hiram's Hospital and precentor of Barchester Cathedral, in the fictional county of Barsetshire.

Hiram's Hospital is an almshouse supported by a medieval charitable bequest to the Diocese of Barchester. The income maintains the almshouse itself, supports its twelve bedesmen, and, in addition, provides a comfortable abode and living for its warden. Mr Harding was appointed to this position through the patronage of his old friend the Bishop of Barchester, who is also the father of Archdeacon Grantly to whom Harding's older daughter, Susan, is married. The warden, who lives with his remaining child, an unmarried younger daughter Eleanor, performs his duties conscientiously.
