The Prince's Life Regiment (Danish: Prinsens Livregiment) was a Royal Danish Army infantry regiment. The motto of the regiment was "Gloria Finis" (Honor above all).
Because one of the regiment's antecedents was the life regiment of Queen Ingrid, the Queen Mother, the regiment had both Prince Henrik's and the late Queen Mother's cyphers on its Regimental Colour. The regiment was raised during the reign of King Frederik III in 1657 under the command of Ernst Albrecht von Eberstein. Over the years it underwent many changes of name, the last taking place in 1961.
The Regiment participated in the Northern Wars (1657–1660), Scanian War (1675–1679), Great Northern War (1709–1720), First Schleswig War (1848–1850) and Second Schleswig War (1864). It was furthermore in foreign service during 1689–1697 and 1701–1714. The regimental flag had the battle honours Nyborg 1659, Wismar 1675, Rygen 1715, Treldeskansen 1849, Dybbøl 1849 and Dybbøl 1864.
From the 1960s to 2000 the regiment had two mechanised and two infantry battalions, from 2000 to 2004 it had four mechanised and three infantry battalions.
In 2000, two other regiments, Schleswig Regiment of Foot and Queen's Life Regiment, were merged into Prince's Life Regiment. In August 2005, the regiment was amalgamated with Jutland Dragoon Regiment and its battalions were disbanded.
