Major Charles Peter Allen, PC (2 December 1861 – 18 September 1930)[2] was an English Liberal politician who represented Stroud from 1900 to 1918.

He served his country during World War I, as a major in the Gloucestershire Regiment, and as a sportsman played international rugby for Wales.

While an MP, Allen was made a Privy Councillor,[4] and was appointed a deputy lieutenant of Gloucestershire in 1911.

Allen had been a member of the 5th Battalion, Gloucestershire Regiment in the Territorial Force prior to the outbreak of war, and at the age of 53 he became a full-time soldier, helping to raise the 2/5th Gloucesters.

In 1884, Allen was selected to play for Wales in the opening match of the Home Nations Championship against his birth country, England.
