Division General Pedro Pablo Dartnell Encina (December 24, 1873 – September 26, 1944) was a Chilean military officer and member of the Government Junta of Chile in 1925.

During the 1891 Chilean Civil War, Dartnell served with the corps of military engineers, and joined the ranks of the Congressional Army.

In 1910 he was sent again to Europe, this time as a student to the Ècole de Guerre, in Paris, where he studied until 1912.

This junta ruled until March 20, when President Arturo Alessandri Palma reassumed his functions.

In 1930 he was elected Senator for the "Talca, Linares and Maule" district, but only remained in Congress until its dissolution by the Socialist Republic of Chile on June 4, 1932.
